The best full-tower case in 2021

Think of the best full-tower case as a clubhouse for all your valuable PC parts. These towering towers are meant to provide enough room for your CPU to breathe along with being able to accommodate larger components like the colossal RTX 3090. This also gives to the freedom to experiment with more elaborate cooling options like custom water cooling loops should you feel adventurous.

Treat yourself with an Extreme gaming PC build.

Full-tower cases are the best options for anyone with the 'everything and the kitchen sink' approach to building a PC building. Imagine, if you will, room for an EATX motherboard, the best graphics card, all the SSDs and HDDs you can afford, and more fans than you can count. 

When choosing a suitable full-tower case, a lot of it will come down to personal taste.   Just consider everything you need in a good PC case, like ensuring you've got enough clearance for your GPU and decent airflow. However, you should note that these large cases also come with hefty price tags. So, if cost is a concern or you're trying to make the best budget PC, consider one of the best mid-tower cases to make your wallet happy. 

We've listed our favorite full-towers that we've tested this year and wholeheartedly recommend them for your future PC build. Alternatively, if you want to look at the other end of the scale, we also have a guide to the best mini-ITX cases for those small form-factor builds. And, if all this custom build stuff scares the living hell out of you, check out our guide to the best gaming PCs and score yourself a nice prebuilt PC.

1. Corsair 1000D

The biggest and baddest of them all

Form Factor: Super tower | Motherboard Support: ATX, Extended ATX, Mini-ITX, SSI EEB, microATX | Dimensions: 27.4 x 12.1 x 27.3 inches | Weight: 29.5kg | Radiator Support: 120mm; 140mm; 240mm; 280mm; 360mm; 420mm; 480mm | I/O Ports: 1x Audio/Mic, 4x USB 3.0, 2x USB 3.1 Type-C | Drive Bays: 6x 2.5-inch, 5x 3.5-inch

Supports just about any crazy build
Can house an E-ATX and Mini-ITX build at the same time
Supports dual 480mm front radiators
Space eater

There are big cases; then, there are big cases. Actually, to describe this case as big would still be an understatement. The Corsair 1000D is bigger than what many would define as a full-tower. It's so enormous; Corsair calls it a super tower. It's a behemoth of a PC case, ready to house the biggest and baddest systems. Standing tall at a staggering 27.3″, this super tower features enough space to house 18 fans and up to four massive radiators simultaneously.

In addition to the insane cooling support, the 1000D features a unique triple-chamber design with convenient French-door-styled storage compartments and telescoping radiator trays for easy installation. It's a case that is so massive; it can house both an entire E-ATX build and a mini-ITX build at the same time.

Because it is 2021, of course, there is also an RGB-lit front panel I/O with built-in smart lighting and fan control courtesy of Corsair's Commander Pro controller. The Obsidian 900D has long been a top choice for massive, over-the-top builds, and it only fits that the 1000D would come along to knock it off its throne.

2. Cooler Master Cosmos C700P

The best full-tower case for flashy builds

Form Factor: Full-tower | Motherboard Support: Mini-ITX, Micro-ATX, ATX, E-ATX (Support 12″ x 11″) | Dimensions: 639 x 306 x 651mm | Weight: 22.2 kg | Radiator Support: 120mm; 140mm; 240mm; 280mm | I/O Ports: 1x Audio/Mic, 1x USB 3.1 Gen 2 Type-C, 4x USB 3.0 | Drive Bays: 2x 2.5-inch 2, 8x 3.5-inch

Integrated RGB lighting system
Adjustable motherboard layout
Potential cable routing hurdles

The C700P, like the original Cosmos, is one of Cooler Master's largest enclosures and comes with an equally hefty price tag. The premium case maintains the same handlebar design as the original but adds a few modern touches that make it one of the most beautiful cases we've seen.

A pair of understated RGB light bars system in the top and bottom of the case illuminates the exterior in a tasteful manner that doesn't distract from the overall aesthetic of the build. Another upgrade from the original is a new curved tempered glass panel that allows you to showcase a gorgeous interior.

As expected from a premium case, the new Cooler Master Cosmos features support for the most high-end components, including E-ATX motherboards, multiple oversized graphics cards, and radiators up to 420mm in length. The only minor problem we found with the size and capabilities is the potential issues with routing accessories and power cables with specific motherboard tray configurations. It'd be great to see Cooler Master include some extensions for this.

Highly modular
Wireless Qi charger
Extensive cooling support
Modular = fiddly

Initially known for their silent power supplies and fans, be quiet! entered the case market with a big splash and has done well in a short period since its first case launch in 2014. One of the company's newer cases, the Dark Base Pro 900, remains one of our highly recommended full-towers thanks to its sleek design and enthusiast-friendly interior.

The case is one of the most modular cases we've ever seen. You won't find too many rivets in this one. Instead, just about every single panel can be removed, making this case a modder's dream. There's also a lot of customization available with options for an inverted motherboard layout and even some nifty features like wireless Qi charging and preinstalled LED lighting.

The Dark Base Pro 900 is large enough to support the biggest motherboards and radiators up to 420mm in size. It's a huge full-tower that can support just about any custom cooling you can dream up. It also looks very sleek with a few color options to spice things up. Priced around $200, the Dark Base Pro is a rare case but comes with all the bells and whistles to make it worth it.

4. Thermaltake View 71

The best full-tower for tempered glass lovers

Form Factor: Full-tower | Motherboard Support: Mini ITX, Micro ATX, ATX, 12” x 13”(E-ATX) | Dimensions: 592 x 274 x 577 mm | Weight: 18.9 kg | Radiator Support: 120mm; 140mm; 240mm; 360mm; 420mm | I/O Ports: 1x Audio/Mic, 2x USB 3.0, 2x USB 2.0 | Drive Bays: 6x 2.5-inch, 3x 3.5-inch

Tons of tempered glass
Includes three RGB LED fans
Highly modular case
Airflow somewhat stunted by glass front

With RGB now firmly entrenched in the PC building psyche, tempered glass cases are clearly more than a passing fad. Thermaltake’s View 71 boasts four tempered glass panels to show off your LED-soaked skills, and it comes with three RGB LED fans pre-installed as well.

The View 71 RGB is the perfect full-sized tower for RGB enthusiasts. The tempered tinted glass does a great job making internal lighting stand out. And unlike some of the other tempered glass cases we’ve used, the View 71 comes with swinging doors, so you don’t have to remove the entire glass panel every time you want to make a change. 

The case also includes a vertical GPU mount and extensive liquid cooling support for all-in-one and custom loops. If you want a big case with e-ATX support to showcase your components inside, View 71 is the way to go.

5. Phanteks Enthoo Pro

The best budget full-tower

Form Factor: Full-tower | Motherboard Support: ATX, EATX, mATX, SSI EEB | Dimensions: 235 mm x 535 mm x 550 mm | Weight: 13.8 kg | Radiator Support: 120mm; 140mm; 240mm; 280mm; 360mm; 420mm | I/O Ports: 1x Audio/Mic, 2x USB 3.0, 2x USB 2.0 | Drive Bays: 7x 2.5-inch, 6x 3.5-inch

Great cable management
Supports several liquid cooling options
Affordable large tower
Outdated aesthetic

When it comes to PC cases, Phanteks is one of the most underrated brands around. The company is slightly newer to the scene, but they've done a fantastic job making things easier for first-time builders and enthusiasts alike. The Enthoo Pro is one of our favorite full-sized towers.

Phanteks was one of the first manufacturers to include pre-installed cable management ties. This little feature makes a world of difference when it comes to the tedious task of keeping your cables in check. The case also offers a ton of flexibility, which makes it great for all sorts of large builds.

Out of the box, the case comes with a 200mm fan in the front panel and a 140mm fan in the rear. This is enough to provide quite a bit of airflow in the case, but the top panel lets you take things even further with support for a radiator up to 420mm in size. Priced at just under $90, the Phanteks Enthoo Pro is a fantastic value and beefy enough to support a wide variety of full-sized builds.

Best full-tower case FAQ

What to look for in a full-tower case?

Aside from looking good on your desk, there are a number of key features you should consider before picking up a full-tower case. First off and most important is airflow and cooling. You need to make sure there’s enough space to install fans or liquid cooling radiators. An overheating PC could have devastating effects on performance. 

You need to see if your future full-tower case has room for your video card. Not all GPUs are created in the same size so knowing the length of your GPU ahead of time can save you a headache. 

Some full-tower cases have special sections to routing and hiding cables which is a big help if your cable management skills aren’t the best.
