There are some truly amazing-looking PC cases out there for those looking to build their ultimate dream rig, but sometimes the options seem too expensive. Luckily, a healthy market of sub-$100 options that still look awesome and have all the features the keen PC builder would want like fans, space, sound-proofing, and just overall style.
High quality
Phanteks P400S
Staff favorite
This is a stunning mid-tower, sporting ample room for even the largest of GPUs and has a bunch of features that make for a stunning PC build. It comes with two 120mm fans and supports up to a 360mm radiator, along with full-sized power supplies. Plus, it has soundproofing included for a quieter build. The full-length tempered glass side panel will show off your handiwork to all who gaze upon it.
Small-form
Thermaltake Core V21
Little cases like Thermaltake's Core V22 are perfect for media PCs and storage boxes. It can fit an M-ATX or Mini ATX motherboard and accompanying components, but there's ample room in such a small chassis just in case you want to throw in a GTX 1080. Another bonus of the Core V21 is the price, which as you can tell, is quite low compared to others on this list.
Affordable RGB
Phanteks P350X
Despite being small, there's plenty of space for an ATX build, with hidden drive cages in the base and at the back of the motherboard tray. The P350X features a tempered glass side panel joined by an RGB strip running along its base, along with two further RGB strips on the front. Each side of the front panel is covered in mesh so you're getting solid airflow, and it supports dual 120mm or 140mm fans in the front or a 280mm radiator.
Spacious cube
Thermaltake Level 20VT
You may think it impossible, but this case has four tempered glass panels for under $100. Inside you'll be able to build a stunning micro ATX system packed with drives and liquid cooling. You can even move the panels around to suit your particular design. Even with all that glass, you get great airflow, and you'll never be bored of looking at your PC in this case.
Super sleek
InWin 101
This sleek case isn't just a great price or amazing to look at, it's also pretty innovative in its design, especially for a sub-$100 price point. It can house a full ATX build, the largest graphics cards on the market with its dedicated GPU holder for added support, and most of all, the power supply chamber is in the roof. This promotes better airflow, which combined with up to six case fans should keep your rig nice and cool.
Looking sharp
NZXT H510
NZXT's PC cases are always head-turners, and the sharp lines of the H510 are no exception. This mid-tower packs everything you'd want for a high-class build. It's available in different colors, has a pretty elegant cable management system, a pair of 120mm fans included with support for full water cooling setups and a three-quarter tempered glass panel, plus USB-C on the front I/O panel. It looks pretty special with some RGB lighting, too!
Silence is golden
Cooler Master Silencio S400
You might think you have to pay a significant premium to get a super-quiet PC case, but that's far from the truth. True to its name, the Silencio has sound dampening material on the front, sides, and top. There's no tempered glass here, but the front door can be reversed to open whichever way you desire, the top can be removed for added ventilation, and it comes with a couple of 120mm silent fans to get your build going.
Premium design
Lian Li Lancool 2
A Lian Li case for under $100 is not to be ignored. The Lancool 2 has RGB panels at the front, tempered glass on both sides for easy access, and a really clean, neat cable management solution. It's big enough for a full ATX build, even the larger E-ATX size, and has a bunch of flexibility to help you get your build just right.
If we had to choose...
Building a great PC doesn't have to mean spending hundreds of dollars on a case anymore. The sub-$100 market is packed with amazing choices like the Phanteks P400S and InWin 101 to name but two. Saving money on one of these great cases will allow you to spend more where it really matters; on what goes inside it.
But in both cases you still get a high-quality product that looks good on the outside, has plenty of space for a pretty sizeable build inside and lots of scope for cable management. It has to be good to build in as well, and these are.
It's also worth considering the Phanteks P350X. It has much of what its more expensive sibling does, including E-ATX support for the largest of consumer motherboards. Add in a sprinkling of RGB, great cable management and a ridiculous number of drive caddies, it's an excellent case to build in on an even tighter budget.
