When it comes to finding the best PC case for you, there’s a lot to consider. First and foremost you’ve got to be thinking about good airflow. Keeping your hardware cool, and noise levels as low as possible is paramount to good system performance and your own peace of mind. There’s a lot to consider when choosing the best PC case, even in that small facet of case design. A mass of variables affect it, from the number of included fans (and total fan mount locations), to sound dampening material, and overall shape and design, the list is endless. 

And then there’s size. Are you looking for a cupboard-sized super tower, or a shoe-box-like ITX chassis? Choose the best PC case for you and it’ll serve you well through multiple builds, plus save some hard earned cash in the long-run. That said, with hundreds of available chassis, models and variants, where do you even start? Well you’re in the right place. 

Quick Shopping Tips

  • Figure out what parts you have/want first. Aesthetics are important, but before you get to that, you’ll want to know what motherboard, graphics card, and cooler you’ll be using, plus how many drives you’ll want to install. This will dictate the size and shape of the cases you should be considering.
  • You probably don’t need a huge tower. Multi-card setups are on the wane, storage is always getting denser (plus with an M.2 SSD, your SSD is physically smaller than ever), and coolers are getting more efficient. So unless you are building a component-packed workstation or you just like the looks and upgradability of a full-sized tower, something smaller will probably the best PC case option for you.
  • Cooling is key, especially in small cases or with lots of components. Airflow is important in choosing the best PC case, especially when it comes to high-end components in tight spaces. Check our cooler reviews for our cooling test results before buying, and remember that cases with tempered-glass fronts and tops often restrict airflow and may require additional fans.
  • Tiny cases are tougher to build in. This is especially important if you’re a novice builder, but even veterans can find it tough to fit components in a small Mini-ITX chassis, as we experienced when birthing our RGBaby. There’s no doubt that compact builds with powerful parts are impressive and space-saving. But remember to set aside extra time and patience—and double-check those key component dimensions—before attempting to build a tiny PC.
  • Choose a chassis that you like to look at. Unless you don’t care about aesthetics at all and are going to shove your new system far under your desk, it's likely to spend lots of time in your peripheral vision. Don’t forget to check airflow and that your parts will fit. But after that, find something that appeals to you visually, whether that be a glass-enclosed rainbow of RGB LEDs, or a simple black box with smooth lines and lots of top-mounted USB ports. There are tons of case options out there. You should take the time to find one that appeals to you visually.

Lian Li Lancool II Mesh (Image credit: Tom's Hardware)

2. Lian Li Lancool II Mesh

Best Mid-Range ATX Case

Type: Mid Tower ATX | Motherboard Support: Mini-ITX, Micro-ATX, ATX | Card Length Supported: 15.1 inches (384mm) | Storage Support: (4) 2.5-inch (3) 3.5-inch | Included Fans: (2) 140mm, (1) 120mm

Excellent thermal performance
Thoughtful interior
Ingenious cable management
Three included fans with controller
No RGB (a pro, for some)
Exterior design is a bit boring
USB-C costs $15 extra

If you’re in the market for a no-fuss, built-like-a-tank, high-performance, competitively priced PC case and don’t mind this model’s somewhat boring appearance, we can do nothing other than recommend the Lian Li Lancool II Mesh.

Aside from being a great performing case, the Lancool II Mesh is also a dream to work in and offers unparalleled flexibility. The case is heavy, but feels extremely solid and is clearly meant to last.

Phanteks Eclipse P300A (Image credit: Tom's Hardware)

3. Phanteks Eclipse P300A

Best Budget ATX Case

Type: Mid Tower | Motherboard Support: Mini-ITX, Micro-ATX, ATX | Card Length Supported: 355mm (14 inches) | Storage Support: (2) 3.5” (1) 2.5” | Included Fans: (1) 120mm ARGB

Great airflow
Easy to work in
Loud performance under load
Only ships with one fan
No USB Type-C or RGB

If the Phanteks Eclipse P300A had a motto, it would be "less is more." It succeeds at what it aims to do well and is an excellent choice for a beginner builder. It's a simple, minimalist budget chassis at a nice $60 price.

Its mesh front panel also lends the chassis to a highly airflow-optimized design. Despite that it only comes with one fan from the factory, performance is acceptable thanks to the mesh front. We would still recommend adding at least one fan to blow air onto the GPU if you can spare the expense, but it’s worth noting that our test bed with the i9-9900K and the 2070 Super is far beyond what most shoppers in this segment would throw at this case, and the P300A’s single fan still managed to keep temperatures in check.

NZXT H400i

4. NZXT H400i

Best MicroATX Case

Type: Mini Tower | Motherboard Support: Mini-ITX, Micro-ATX | Card Length Supported: 411mm (16.2 inches) | Storage Support: (1) 3.5", (4) 2.5" | Included Fans: (3) 120mm

Good-looking tempered-glass design
Strong thermal performance
Included RGB lighting and fan control
Reasonable price
Slightly noisy at full fan speed
No front-panel USB-C ports

Excellent performance, good-looking design, included RGB and fan control, and competitive price tag come together to make the H400i an excellent choice for MicroATX builders. The case gets a little noisy with fans running at top speed, and there’s no USB-C ports on the front panel. But if those shortcomings sound reasonable to you and your motherboard is smaller than full-size ATX, this case should be on your short list.

Cooler Master Silencio S400

5. Cooler Master Silencio S400

Best Budget MicroATX Case

Type: Mid Tower | Motherboard Support: Mini-ITX, Micro-ATX | Card Length Supported: 319mm (12.56 inches) | Storage Support: (4) 3.5", (4) 2.5" | Included Fans: (3) 120mm

Whisper quiet operation
Sleek design
Solid build quality
Reversible front door
SD card slot
5.25-inch ODD slot
Below average thermal performance
No USB 3.1 Gen 2 Type-C
Front radiator support may require hard drive rack removal

We don't often find a case that's lined with sound damping sheets for under $100, let alone one that has a damped front panel door with reversible swing. The Silencio 400 offers these, plus a hidden front panel device bay and adequate dust filtration, along with a classic look. Despite its slightly higher-than-average temperatures, the case's exceptionally reduced noise gave it a great performance balance that could be perfect for your low-noise environment.

NZXT H1 (Image credit: Tom's Hardware)

6. NZXT H1

Best Mini-ITX Case

Type: Ultra Compact Desktop | Motherboard Support: Mini-ITX | Card Length Supported: 305mm (12.01 inches) | Storage Support: (2) 2.5" | Included Fans: (1) 140mm

Easy installation of hardware
Includes 650w SFX PSU and 140mm AIO liquid cooling
Compact footprint
Supports only mITX motherboards
No support for additional fans

With a base that's under 7.5-inches square and a height of just over 15 inches, the H1 from NZXT packs a lot of hardware into an incredibly small footprint. Concerns over its incredibly large price are mostly addressed via its inclusion of NZXT's 650w, 80+ Gold SFX modular power supply and built-in 140mm AIO liquid cooling system. Those custom fit components leave builders free to assemble their machines without the need to purchase custom-length cables, as may have otherwise been required to fit so much hardware into so small a space. With support for both AM4 and LGA 1151 processors plus graphics cards up to 12" long, limitations are primarily left to your imagination.

Cooler Master Cosmos C700M

7. Cooler Master Cosmos C700M

Best High-End Showcase PC Case

Type: Full Tower | Motherboard Support: Mini-ITX, Micro-ATX, ATX, (E-ATX support up to 12 x 10.7 inches) | Card Length Supported: 490mm (19.3 inches) | Storage Support: (5) 3.5” (4) 2.5” (+ 5x converted from 3.5) | Included Fans: (4) 140mm

Excellent thermal performance, liquid cooling support and cable management

USB-C port
Multiple GPU configurations
Includes GPU riser cable and four 140mm fans
Requires two USB 3.0 headers or a 20-pin splitter cable for all four front panel USB 3.0 ports
Reconfiguring the motherboard layout may be tough for beginners

You couldn't ask for a more full-featured, future-proof chassis than the Cooler Master Cosmos C700M. Even with the higher than average price tag, the case's thermal performance, integrated ARGB lighting, multi-layout design and laundry list of features definitely justifies the asking price.

Not everyone can or should spend $440 on a case, but but this is a specialized, high-end chassis specifically built for enthusiasts willing to spend their hard earned money to have the best. And make no mistake about it, the Cooler Master Cosmos C700M is one of the best.

be quiet! Dark Base 700

8. be quiet! Dark Base 700

Best XL/EATX Case

Type: Mid Tower | Motherboard Support: E-ATX, ATX, Micro ATX, Mini ITX | Card Length Supported: 286mm (11.2 inches)/430mm (16.9 inches with HD cage removed) | Storage Support: (7) 3.5, (9) 2.5" | Included Fans: (2) 140mm

Good thermal performance
Great looking chassis
Embedded lighting
Tempered-glass side panel
Low noise
Excellent filtration system
Only two 140mm fans (three would be ideal at this price)

The be quiet! Dark Base 700 is in a class of its own. At first glance it may seem like just another case with a tempered-glass side panel. But upon further inspection, it’s clear how much time and effort went into the design. You'd be hard-pressed to find a more versatile, high-performance enclosure.

It’s clear that be quiet! put a great deal of thought into the design of this chassis’ filtration system. Every intake fan mounting location in the Dark Base 700 is equipped with a washable nylon fan filter. Gaining access to filters requires removing the front panel, but even though the front and bottom filters are extremely long, maintenance and cleaning is a snap.

Phanteks Enthoo Pro II (Image credit: Tom's Hardware)

9. Phanteks Enthoo Pro II

Best Dual-System Case

Type: Full-Tower ATX | Motherboard Support: Mini-ITX(2), Micro-ATX, ATX, E-ATX | Card Length Supported: 19.8 inches (503 mm) | Storage Support: (12) 3.5", (11) 2.5" | Included Fans: None

Excellent thermal performance and cable management
Flexible interior and lavish front I/O
Affordable for its size and features
Unnecessarily big
No fans included
Materials could be of higher quality

Phanteks’ Enthoo Pro II is a very unique chassi, offering the most seamless dual-system support we’ve ever seen. And its new fabric mesh front looks really great, especially when you get close to the case. 

Thermally and acoustically, the Enthoo Pro II also performs phenomenally well. Of course, the mesh does let more noise out than a closed-front case would, but if you’re careful in your component selection and only pick quiet parts, it should all remain very tolerable.

    In the info block at the top, the "review" link for the H200i goes to the Define R6 review; it's correct at the page bottom.

    Why are front panel USB ports, power switches, activity lights, etc. placed on top of cases? If I interpret correctly a desktop computer indicates it is placed on your desktop. My last 3 or 4 cases had everything on top and I couldn't see them without standing up and the hard drive activity light was out of sight while I'm sitting in my normal position. I wish they would start putting front panel stuff on the front panel and not on top of the case.

    Why isn’t Phanteks on this list?
  • Lucky_SLS
    The pc O11 dynamic will get a 2/5 in Tom's review cuz they test it at stock fan configuration. Maybe that's why it's not in the list XD.

    But you still have the pc o11 air and Lan cool one to test! Reviews for the lancool one digital asap plz!

    A lot of cases aren't available in this part of the world and computer parts are priced at 50% or higher premium against US prices. Amongst those that were, I found Corsair Obsidian and Corsair Carbide cases generally good but overpriced. Personally I liked the Corsair Obsidian 750D most, but purchased what I consider the next best case and much better value for money - the Antec 1100 V2. Being the first desktop I assembled myself, the Antec 1100 made the job a lot easier.

    Why do so many of the top cases have glass panels? Glass is a bit of a thermal insulator, add unnecessary weight, and serves no practical purpose in a PC case. If you want to see all your gear, don't bother putting it a case.

    I had the Lian Li A20. It was an expensive beast, and a damn good case, but i find Fractal Design's cases to be more practical, same build quality - if not better, and definitely quieter.

    The thin aluminium of the Lian Li was prone to vibration.

    It's a legacy name thing from a time when your CRT monitor sat upon a PC case that was designed to be laid flat & sit on a desk. It then served as a distinction between laptops & other equipment.

    If you have your mid-tower case on your desk you are doing it wrong.
    Its noisier and it eats up valuable desk real estate. Its a big stupid box on a desk - F it off.

    'But how else can we look at the purty lights?!' they might ask. That's where it all went wrong.
