As far as aesthetics go for your next build, nothing is more important than the chassis.

There are plenty of great PC cases out there (in all shapes, sizes, and colors).

But in terms of design, they can often feel like they blend into each other.

So what about those who want something a little….different?

Our latest feature breaks down the most unique computer cases available today that you can actually buy (not just one-off mods that cost 1,000s).

Best Mainstream/Affordable Choices

Craziest PC Cases

Best of the Rest

Best Mainstream/Affordable Choices

This feature is broken into three parts – the first is for the most unique PC cases with some consideration for availability and affordability.

Skip over to the Craziest PC Cases section if you’re more interested in the most innovative, unusual designs.

Overall Best Unique PC Case: Corsair Carbide SPEC-Omega

The SPEC-Omega tops our list with its ability to strike an amazing balance between price, build quality, features, and of course, uniqueness.

On the surface, it has a rather normal shape and tower presentation.

However, the front and top panels give a deceptive depth to its unique design.

With the dominant sides of the front and top consisting of high-quality steel, the case feels as solid as it looks.

The less dominant front side offers a thick tempered glass preview into the case, with the top offering a mesh view in.

It’s not uncommon to see cases with visible fronts or tops, but being done in this “diagonal” way with the slick RGB divider is special.

Stock photos don’t do this unique tower justice.

When you have gorgeous components shining through its design, you’ll see why we rank it so highly.

The tower also has some gorgeous additional color options, topping our list of red PC cases.

But it gets our top mainstream pick not just for looks, but performance.

With 7 expansion slots, VGA lengths up to 370mm and 3 x 3.5″ + 2 x 2.5″ drive bays, this unique ATX tower has great space for a wide variety of builds.

There are some great cooling options too, with:

  • Air: 6 x 120mm fans – 2 high-quality Corsair SP120L fans included
  • Water: 1 x 360mm, 1 x 240mm & 1 x 120mm radiators

Combined with its great internal design/cable management capability for airflow, we rank this as one of the best unique PC cases for gaming with all of the overclocking possibilities.

While there are some crazier designs further in the list, if you’re looking for a unique chassis that also offers so much capability and quality for its price tag, this is an amazing choice.

Runner-Up Best Unique PC Case: Thermaltake Core P3

Oh boy, we love this case.

Featured several times previously on What in Tech for its amazing capability, the P3 is the perfect unique case if you’re looking for high visibility.

It may look simplistic, sure.

But its uniqueness comes from its ability to show off your beautiful internal parts as no other case can.

The P3 has 4 open sides and a thick, tempered glass covering.

This design is great not just for looks but also for ventilation.

Not to mention this is by far the best wall-mount PC case if you want to make your setup extra unique.

If you want a different size/more intense unique build, check out the different P-series options in the product listing (P1P90) – we talk through some of the key differences here.

The case excels in space too due to its minimalist design, with:

  • 8 x expansion slots (and options for vertical GPU install)
  • Graphics cards up to 450mm length (with radiator reservoir removed)
  • Hidden 2 x 2.5″ or 3.5″ + visible 2 x 2.5″ or 3.5″ drive bay
  • Cooling: 3 x 140mm fans or 1 x 420mm radiator

With the open ventilation, you don’t need the 6-7 fans you usually see in an ATX case.

The P3 performs just as well, if not better in cooling, making it such a great option for gaming and enthusiast builds.

Simply put, if you know you’re building some unique looking components and want a cool gaming case to present them, you won’t get a better/more unique offering than the P-series.

Best Unique Budget PC Case: Thermaltake Versa N24

Now, if you were thinking you couldn’t find a cheap unique PC case good enough for your build, we’re here to happily prove you wrong!

Looking like it came out of Fallout or Midgar, the Versa N24 design is fantastic.

We love all of the intricate edges, pipes, and different panels around this futuristic PC case.

With the cheap price tag, you’re not getting the same build quality as other cases on the list, with a cheaper metal window and plastic exterior.

Though the case still feels great for the price tag, and what’s more, it has a lot of space capability, with:

  • 7 x expansion slots
  • VGA lengths up to 415mm (with a front fan removed).
  • 1 x 5.25″, 2 x 2.5″ / 3.5″ & 2 x 2.5″ drive bays
  • Up to 6 x 120mm fans (1 pre-installed, great for the price).
  • Or up to 2 x 240mm & 1 x 120mm radiators

As you can see from the size/cooling availability, this is a capable unique gaming PC case.

If you were building a crazy, multi-GPU setup, we’d steer you to one of the more expensive offerings for cooling.

That being said, if you’re building a budget PC, this case will perform excellently for what you’re after.

Rest assured – if it’s the furthest your wallet can go, this is the best unique budget PC case available.

Best Unique Micro ATX Case: Silverstone SG12

For the smaller mATX form factor, there aren’t as many interesting options available.

Thankfully, Silverstone, who specializes in alternative horizontal PC cases, has created a striking cube chassis.

With a high-quality aluminum front and steel body for the rest, the case has an awesome gunmetal grey finish with some roughness to it.

This contrasts with the sharp blue bar on the front, which doubles as a handle-bar to carry the PC case portably.

If you check some of the product photos that show the internal layout, you’ll see why we tout this case as special.

The structure of the SG12 is very unique, but not just for the sake of standing out, it’s cramming in great space for:

  • 4 Expansion slots
  • VGA cards up to 368mm length
  • 1 x 5.25″, 3 x 3.5″ & 9 x 2.5″ drive bays
  • Up to 2 x 80mm & 1 x 120mm fans

Now while these specs may not seem impressive next to many of the other top picks, bear in mind this isn’t just an mATX case, but one with tight dimensions due to its cube size.

It would be better to go with one of the ATX cases we discuss for a serious gaming build.

That said, if your unique tower searches are for an HTPC, video editing, or general usage build, this cool computer case is fantastic. Particularly for the first two (given the ridiculous amount of available storage space).

Best Unique Mini-ITX Case: NZXT H1

2021 Update: The NZXT H1 is temporarily unavailable for sale due to an issue with the GPU riser – NZXT has confirmed that they are working on a new iteration which is why we are still displaying this review for when it comes back. In the meantime, some of the coolest mini ITX case alternatives are the InWin A1 Plus (review here) & the SilverStone LD03B (this choice is the most similar option to the H1).

On the surface, the H1 may seem like a pretty ordinary vertical tower.

But for its form factor? All of the H1’s serious competitors are cube/short cuboid shapes.

NZXT has created a truly unique innovative space inside the H1 to allow such a low volume “console-shaped” PC case to exist.

The build and design are simply awesome, with a high-quality SGCC steel exterior and tinted tempered glass that will sleekly display the interesting inner layout of the H1 combined with your components.

With what feels like wizardry for its dimensions, the H1 has:

  • A PCIe 3 riser card to vertically install a GPU
  • 2 x expansion slots / GPU lengths up to 305mm
  • 2 x 2.5″ bays (many larger ITX cases only have 1)

The fact that you can install most mainline GPUs in a case of this size is incredible, and the vertical layout will give it a truly unique presentation.

The case comes with a high-quality PSU specifically designed for the case (so isn’t wasting any space trying to cater to multiple PSU sizes).

You’re also getting a pre-installed AIO 140mm Water Cooler; which combined with the great dual-chamber layout, is designed to be the only cooling in the case (and it’s all you’ll need).

Of course, in a Mini ITX build, you’re not going to have a dual-GPU overclocked setup, anyone with knowledge of the form factor will understand this.

It may seem like a high price tag, but for the build quality, design & included PSU/cooling solution, this really is a great deal.

If you’re looking for the best unique Mini ITX case for gaming or other portable uses, you’ve found it.

Best Unique PC Case for Performance: Corsair Crystal Series 680X RGB

One of the most featured cases on What in Tech, the 680X has so much going for it.

Let’s start with its unique design.

This Corsair tower is the top premium dual chamber PC case available.

This means it has a separate “hidden” compartment designed to hide your “uglier parts”.

Think PSUs and drives.

Not just for presentation, but to improve airflow and room for parts in the main case.

The build quality is some of the best available today.

With a very high-quality steel exterior and thick tempered glass on the front, top and hinged side-panel (full length), the case is truly gorgeous.

Similar to some of the others, the uniqueness of this case isn’t done justice by the stock photos, it really shines when fully built.

But it’s not just pretty…

This is one of What in Tech’s overall top picks for much more than its innovative design, which is why we give it the top performance pick.

Perfect for high-end gaming/production builds, you’ll have room for:

  • 10 expansion slots (2 vertical mounted)
  • VGA cards up to 330mm
  • 3 x 3.5″ + 4 x 2.5″ drive bays (all in the 2nd “hidden” chamber)
  • Air cooling: Up to 8 x 120mm fans (with 3 very high-quality Corsair LL120 fans & controller included)
  • Radiator support: Up to 360mm front, 280mm top 280mm bottom & 140mm rear

We love the specs the 680X achieves out of its already well ventilated dual-chamber setup.

Tied with a good motherboard, this chassis will be perfect for not just a powerful multi GPU gaming build, but also for overclocking with the fantastic cooling.

And with the fantastic addressable fans included alongside the beautiful design, you really have a special look going for you.

This is a premium case, and the price is high.

But when you’re balancing an amazing feature set, high-quality RGB inclusion, and beautiful unique design, we know this cool PC case is worth every cent.

Craziest PC Cases

The above picks were special cases with some consideration for being widely available and affordable.

Now, the next section is more about offering the craziest computer cases that money can buy.

Note that while you are paying a premium for their awesome designs, we’re still only recommending cases that offer great value and performance.

Some towers (like the Keider Open Case & darkFlash Knight) look very special, but have some quality problems – trust me, you don’t have to sacrifice good performance for a cool design.

Most Unique PC Case: Antec Torque

OK, now we’re getting to some truly crazy PC cases…

The picture speaks for itself!

Antec really is at the top of their innovative design game with the Torque.

The case is designed to look as unconventional as possible without compromise to the functionality.

With an exterior made of 14 uniquely curved aluminum panels and double-sided tempered glass, the finish of every surface is incredibly high quality.

While the Torque looks great in pictures, it’s a case with high visibility,  which means it really shines when built/powered on, especially with an RGB aesthetic.

This unique ATX case has space for:

  • 7 x expansion slots
  • Graphics cards up to 450mm length
  • 1 x 2.5″ & 1 x 3.5″ drive bays
  • Compatible with EATX motherboards up to 12″ x 11″
  • Up to 6 x 120mm fans or 2 x 360mm Radiators

Despite the focus on design, you still have space in here for an SLI/Crossfire build should you desire.

The only spec lower than we’d like is the drive availability.

It will be low because Antec will only have bays that can be hidden due to the focus on a highly visible design.

And with that said, unless you are looking for video editing or some other very high storage requirement, this amount will be fine for you.

The cooling may not seem out of this world for an ATX chassis, but bear in mind that, with its highly ventilated design, you’re going to be getting great airflow with either solution type.

So, while it’s the aesthetic that is the big selling point of the Torque, through great innovation, Antec is offering a great balance between form and function.

Yes, this insane PC case is expensive, but you’re paying to have not just great build quality and features, but something truly special and unique.

Runner-Up Unique PC Case: Azza Pyramid 804

Yes, that’s right, your eyes don’t deceive you.

It’s a pyramid PC case.

This Azza chassis, like our Torque pick, is great because it still offers a lot of functionality behind the crazy PC case aesthetic.

But let’s start with the design…

With its very high-quality aluminum, thick SPCC steel, and tempered glass build, it’s one of the sturdiest towers around.

And the finish on the metal (not to mention the sharp, sleek corners) gives it a premium feel that few traditional cuboid PC cases match.

When it comes to space, the Azza is an ATX tower with:

  • 2 expansion slots
  • Graphics cards up to 295mm
  • 2 x 2.5″ + 1 x 3.5″ drive bays
  • Air: up to 4 x 120mm fans with 1 Hurricane II Digital RGB Fan pre-installed at the top
  • Cooling: up to 1 x 360mm radiator at the bottom

The case is designed for a single-GPU build.

Don’t let this put you off; even if you are building a very powerful gaming PC, there are single graphics cards that will give you top performance in all games today.

With the good ventilation offered around the top of the case, the cooling available will be all you need for a single GPU gaming PC.

It’s hard to imagine a more unusual PC case than this pyramid.

But Azza really manages to pull it off, if you have the budget and your desired build can fit, this is a fantastic option.

Best Large Unique Case: Cougar Conquer 2

The Conquer is certainly one of the most unique full-tower cases around.

But then Cougar recently released the Conquer 2 and well….look at this thing.

With a full high-quality metal exterior and 4 thick tempered glass side panels, the case is an incredibly sturdy offering.

So much of the aesthetic is also built around the syncable RGB lighting on the front of the case (and that includes a COUGAR ARGB fan pre-installed).

We’ve been saying this a lot on this feature but; the Conquer 2 is another example of a case not done justice by stock photos.

Just check some of the user builds in the product listing. With some RGB components alongside it, you’ll have something really special.

We love the size that the Conquer 2 offers, with:

  • 8 expansion slots + 2 for vertical install
  • While not officially listed, is reported to fit E-ATX motherboards
  • VGA lengths up to 400mm
  • 2 x 2.5″ & 2 x 2.5″ / 3.5″ drive bays
  • Up to 6 x 120mm fans
  • Or up to 1 x 240mm & 1 x 360mm radiators

The cooling availability is fantastic for an open-air case (which often compromises the amount of cooling available in favor of ventilation).

With the incredible space, this unique tower is a great option for a very high-end multi-GPU overclocking build (or something more modest with better cooling).

One neat extra feature in a case this size that we don’t see much is the detachable inner-chassis designed for making modifications and installation easier.

Don’t underestimate the convenience of this feature, everything from cleaning to cable management will be made easier by this luxury.

This is the kind of weird PC case that is so unique, we’re sure some people will love it, and some people will think it’s too much.

But that’s what we think is so great about it; and why it’s perfect for a powerful build if you want something truly one-of-a-kind.

Cool PC Case Alternative: InWin D-Frame

InWin has created one of the best innovative PC cases around in the D-Frame.

We’ve featured this awesome chassis multiple times on What in Tech, with its ability to still offer great performance despite the design focus.

With the unique tubing and base made out of high-quality aluminum and a beautiful tempered glass window on the front, the build is absolute top-tier.

With its intense open-air case design, you are getting both fantastic airflow and high visibility on your more beautiful parts.

But it also does an excellent job in size, with:

  • 8 expansion slots (with vertical install available)
  • Graphics cards up to 330mm length
  • 3 x 3.5″ + 2 x 2.5″ + 1 x 5.25″ drive bays
  • Up to 4 x 120mm case fans
  • Impressive cable management facility despite the large exposure on most sides.

You’ll have everything you need here for either a powerful gaming PC or something more for production/editing.

We like that it even comes with the option for a 5.25″ optical drive in case you’re after a unique HTPC case.

(Though if you’re like most of us and don’t need it, it can be used for further hard drive space with a convertor, or better airflow).

4 x 120mm fans may not sound like much for an ATX case.

But with its high-airflow design, the D-Frame performs excellently even for high-demand builds.

If the style is to your liking, know that there’s a reason this chassis has had a few iterations and won numerous awards.

It truly is one of the most innovative computer cases around, combining a special aesthetic with great functionality.

Best of the Rest

The picks above are what we’d really recommend on your search for the most unique PC case that suits your next build.

That being said, we’ve included some additional options that are still great and worth considering, in case you have some specific requirements we haven’t covered.


PC Case with Screen Side Panel: iBUYPOWER Snowblind S 19″

Yes, you read that right.

This iBUYPOWER PC case comes with a display inside the side panel window.

One of the craziest tower concepts we’ve seen and capable of running a cool gaming build, this is worth considering if you have some ideas on what the transparent display could add to your setup.

Premium Unique Mini ITX Case: Antec Striker

If you’re looking for an innovative ITX case, this is the best around.

We didn’t give it a top pick because of its intense price for such a small case.

But if you have the budget, its a fantastic offering.

Great Unique ATX Case Option: Anidees AI Crystal V3

This is our “third-best” pick for the top of the list and was very nearly the runner up.

If you’re looking more for a cube PC case or simply like the design, know that this is a brilliant offering and provides great performance alongside its amazing looks.

Unique E-ATX PC Case: Thermaltake Tower 900

We’ve talked above about some options that will “unofficially” support E-ATX.

But if you want a unique PC case that you know will do so with ease, this is the one.

With its “fishtank” design, any PC in here will look like little else – check out our full breakdown on our best EATX case picks.

Crazy PC Case Alternative: Cougar Conquer

In the Conquer 2 review, you may have heard us mention it’s older brother, the original Conquer.

While not quite as striking as the new model, this is still a very innovative PC case with a special, unique design.

If this aesthetic speaks to you more than the others on this list, know that it is still a great case.

Unique Budget Micro ATX Case: Nanoxia Rexgear 2

Last but not least, we mentioned that the options for unique mATX cases are a little slim.

But if your heart is really set on this form factor and you want something more budget-friendly or aligned to gaming, the Rexgear 2 is a good choice.

Final Word

We have come across hundreds of towers at What in Tech, and this is truly the culmination of the most unique PC cases around.

We know some users feel like they need to focus fully on functionality for a case.

But know there’s no shame in taking the aesthetic just as seriously, all the picks above will be great for different types of build users.

Don’t focus on form or function, with an innovative PC case, you can have both!
