  • Solid budget case with a ton of features
Style: AIR 903 MAX (B)
I've bought some budget $80 cases that were not this nice. The build quality, the cable routing and features are all outstanding. I upgraded my son's case from a coolermaster MB320L that was way too small so it was cutting off airflow to, well everything, his cpu, gpu and hard drives were all putting out a ton of heat because the airflow was just bad. Get this, The MB320L is now MORE expensive than this one. Once I switched, all of the temps dropped. He has more fans, his pc is quieter, gets better fps in his games (seriously, temps dropped that much) and fully addressable RGB fans. Ok enough comparing, this case was extremely easy to work with. The side panels come with captive screws that make it near impossible to lose or drop. The tempered glass is a full panel with an internal ps basement to hide all of those cables. The full mesh panels on the front have an air filter (It IS a filter despite what reviewer BigChonk says) that's easy to clean and the top vent has a removeable filter that is magnetic. There is tons of space to fit up to a 360 radiator on the front or top, or both for water cooling. The rubber grommets for cables are a nice addition and the moulded cable management chanels are extremely roomy. The only issue I had with this case is I can't use the usbc port because the motherboard he has doesnt have the right port to connect it to so keep that in mind if you have an older board. I definatly would have bought this case three years ago for my own build if it had been out. I mean honestly it's the little touches like the screws and the fan hub and the magnetic filters and led button (OH HOLD FOR 3 SECONDS to put it in software controled mode) that make this case the frontrunner for the best budget case of 2023. ... show more

  • Worth every penny!
Style: AIR 903 Base (W)
I upgraded my PC from a micro-ATX stock case to this one, and I’m so glad I did. Between upgrading to this case and switching from a single-fan GPU to a triple-fan GPU, my PC’s temperatures have been cut in half. My temps used to be in the 70s and 80s in games such as Overwatch and Horizon Forbidden West, and now they’re in the 40s or MAYBE 50s at most. I also like how there’s a place for just about every cable you can think of, and how the hard drive and power supply are neatly hidden away. The stock fans with this case are nice and quiet, I don’t plan on replacing them anytime soon. If you’re looking for a sleek, inexpensive, and airflow-focused case, this is the one! ... show more

  • Good for the price
Style: AIR 903 MAX (W)
It's big so it fit all of my components with room to spare. Has good airflow, my temps are always where I want them to be, but the stock fans it came with aren't exactly quiet. If noise bothers you then you might want to swap the fans out for something more premium. Cable management was kind of a pain, although I'm not sure if that's the case's fault or my mobo's. ... show more

  • Excellent Case! Excellent Value!
Style: AIR 903 MAX (B)
This ended up being my most exciting component of my recent build. Not only does it check all the boxes that one or at least I want in a case... it includes 4 140 mm fans that move a lot of air and they're extremely quiet. In a $73 value case I expected merely mediocre fans, but I'm impressed... the fans are very good. And most importantly, this case runs extremely cool, not just in my case, but there are some Youtube videos that compare temperatures against the top of the line cases in the $150 range and in all instances this case runs equal in temperatures or even slightly cooler. I have two more 140mm fans that I have on hand that I'm going to add to the case, but with my temperatures I don't need too (without overclocking everything is under 40 C), but it's not going to hurt so I will, but I figured that I would need to get another fan in there to move air out given that it's pulling in air via 3 140mm fans and merely one 140mm exhaust fan, but it already runs perfect as is. I wasn't going for looks, but the case looks very nice as well and structurally it has a very nice quality... much better than a typical budget case. I did a good amount of research on cases prior to getting this case and based on my findings Montech is going to be difficult to compete with. With this new lineup of cases they currently have the best budget/value cases right now. ... show more

  • Very premium case for the price, easy for a newcomer to build with
Style: AIR 903 MAX (B)
This is my first ever gaming PC build and I'm impressed by the quality of this case for the price. As a beginner, I was able to assemble a gaming PC on my own without any help. Just online research and patience. The tower is bigger than I thought it would be, but I'm getting used to its size. I really love the dust filters on the top and bottom, really helps with dust management. I also love how all the fans come preinstalled and already plugged into a fan controller. Which made building as a newcomer so much easier. The fans on the front can be heard when the room is quiet, but if you have a box fan in your room like I do, it overrides the noise from the PC. The fans aren't loud, but don't expect complete silence. The air flow in this case is amazing. Combined with the air cooler for the CPU, I'm getting 24 C idle temps. The airflow is so strong that you can see pieces of dust being sucked up against the front panel, which I wipe off with my hand every now and then. It filters out the thicker pieces of dust from getting sucked into the system. The only complaint I have is I couldn't figure out how to mount the hard drive, even while looking at the manual. I can't fit the bent shaped SATA cable into the hard drive so I had to use the other end of the cable. My other complaint is that some of the front panel cables that need to be inserted to the motherboard are lost in the bundled up wires but I eventually worked them out and got them through the grommet. My last complaint is that the manual doesn't explain at all that the fan controller is included or what it is. As a newcomer builder, I had no idea what it was or what was connected to it. I only learned what it was through videos of people building their PC. But once I learned that it's a fan controller, I appreciated it being there and already setup. ... show more
