The Best Budget Option

J. MeiererFebruary 27, 2024✓ Verified purchase

This case is very affordable, but still manages to hit pretty much all of the major points for being a great case. It has tons of room inside for mounting a GPU, even fitting a 7900 XT with it's huge mounting z-bracket. In terms of space just be careful with 140mm-fan top mounted liquid cooler radiators. There is only about 55mm of clearance before the vram heatsink and a thicker cooler like the 280mm Arctic Liquid Freezer will get inside the case but be unable to line up with the screw holes. Just use a 120mm-fan based radiator or front mount for AIOs. The case comes with plenty of extra screws and the rear slots for the GPU mount are thumb screwed in and not disposable which is a good sign. The stock PWM fans seem nice and are plenty quiet. The front fans come linked together and so they only need one header to plug into the motherboard. If you buy the 903 base you can move the rear mounted fan to the front to have 3 matching intake fans and then buy a new rear exhaust fan to mount. Cable management was very easy with the included raceway and the many holes for routing cables. The case seems stable and I only noticed the slightest deformation when torqing screws. Seems like a great case. Read more

Great case for the price

Rebecca ShoemakerFebruary 11, 2026✓ Verified purchase

Excellent case at this price point. Comes with 2 front and 1 rear 140mm fans. Fits my ATX motherboard and RX 9070 XT nicely. Built mine with minimal RGB on purpose because I like the blackout look. Has easily removable covers for cleaning dust and is nicely appointed with the proper holes and straps for cable management and minimization. Read more

Xander B.February 4, 2026✓ Verified purchase

Is a very good case. 100% The best starter case for beginners. Very easy cable management, good size, etc. Looks good too. Very functional fans aswell, their large size pushes a substantial amount of air Read more

Great buy (AIR 903 Base (B)

BryceMarch 9, 2026✓ Verified purchase

Great airflow, comes with 2 140mm in front 1 in back, with room for more. Cable management is good, has some Velcro fasteners along the back. Front and side panels are easily removed. Looks fantastic. Would buy again 100%! I threw an old Intel dp67bg mobo with a i7 3770 and a Sapphire Nitro + RX580 in it for a 3rd system. Read more

Good Budget Case

B-manOctober 8, 2025✓ Verified purchase

Overall a great case when you want something to look good on a budget. Pros: -Relatively easy to build in -USB and headphone/microphone jacks at the top are fully functional when connected properly -Can easily fit in 140mm fans -Fantastic airflow -Fits a full-size GPU -Has space for 2 2.5" internal HDDs just forward of the PSU -Plenty of space for cables to go through -Should be able to fit most vertical GPU mounts given how many slots it has Cons: -No places for a disc drive for those that care (you can just buy an external anyways) -Location of the HDD bay is a bit inconvenient for cable management -Front mesh panel is a tad difficult to remove and replace when you clean it -PSU Shroud doesn't really prevent dust from getting to it due to all of the holes -Case is a bit dinged up (doesn't perfectly align with glass panel), but that could just be from shipping -USB and headphone jacks being located on top of the case raises some concerns regarding dust, will definitely need some dust covers Read more

Solid case

Mario RodriguezFebruary 12, 2026✓ Verified purchase

Fit all of my parts just fine and the installation process was very easy. Case fans help keep the inside cool so I appreciate that. Overall, it is a great budget option for people who don’t care for RGB. Read more

Good case for the money

DNAugust 4, 2025✓ Verified purchase

Excellent case. Good size to fit most CPU fans and GPUs. Has front panel reset switch which some budget cases don't have. Case cover and expansion slot screws are standard thumb screws. Not as robust as more expensive cases, but plenty sturdy. All in all, a good case for the money. Read more

Best Case for money

Kushendra RamrupAugust 7, 2025✓ Verified purchase

It was exactly the case I ordered, brand new unopened with all parts. A great looking case with tons of room and air flow making cooling no problem, very easy to keep clean as well. For the price I got it at last year it's unbeatable. Read more
