4000D killer, but QC needs to be improved.
Style: Air 903 MAX Black Color: Black
It’s a great package for the price and I would highly recommend it. I got the black 903 MAX version for 70$ on sale, and at that price it simply cannot be beat. The construction of the case feels solid and does not feel cheap, perhaps a slight notch below the 4000D’s overall sturdiness, but still very good. You get nice front I/O including an RGB button, reset SW, premium power button with metal, and USB type C (which I think is the biggest selling point. The cable management in the case is overall very good. I have worked with the 4000D and it is just as good as that. You have included velcro cable ties and a decent amount of tie off points. The included fan hub in the back is an absolute lifesaver for cable management and all of the fans and what not are already connected to it. The only thing you really need to connect from it is the SATA power 6 pin from your PSU to power all your fans. It’s helpful be cause it completely mitigates the amount of fans you have to awkwardly try to plug into your motherboard, it also just really cleans up the rear cable management and makes it much easier to understand which cables go where. The only real cables you have to manage are: your USB headers (type C and A), your very small front panel pinouts (Reset SW, Power SW, HDD LED, etc.), two other small cables (HD audio and and ARGB header), then just your main power cables (24 Pin PSU, 8 pin CPU, 8 Pin GPU/VGA). I did have two minor gripes with the case, though, that I want other customers to be aware of and perhaps Montech themselves. I was using a Micro ATX motherboard in this case and when I went to put the motherboard in the case and had started to screw it down, I finally noticed that the bottom 2 stand-offs were never installed. So I had to take back out the motherboard and install the 2 (3 provided) to fix the issue. So beware that you very well may have to install the standoffs before you put in your motherboard. Second gripe is quality control. I know that I have heard multiple people complain online about how they received cases from Montech that were slightly damaged/defective. On JaysTwoCents review of this case, he also received on with a pretty noticeable dent. Similar to Jay, I also received a small contour in the metal toward the back left of the case. If you looked at if from the right angle, you could tell that the contour/angle was not intended. So I am not sure if these cases are being damaged in shipping or if it is just Montech’s factory QC that is leading to these f defects. But overall, I am happy with the case and am not returning it because the damage was still very minor. I would provide pictures of my build, but I don’t want to give Amazon access to all my photos 🙃 ... show more

Solid budget case with a ton of features
Style: Air 903 MAX Black Color: Black
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

Excellent Case! Excellent Value!
Style: Air 903 MAX Black Color: Black
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

What is Great: This Montech AIR 903 MAX case is built well and looks good. It offers excellent value and is favorably priced. Overall, I do like it and recommend it. Air flow is good. The 140mm fans (four included) are pushing more air than I imagined they would and run very quiet. The PWM fan/RGB hub is a nice feature that works well. I like the included lighting control button. It sucks to have to install trashy OEM bloatware for lighting control and with this case you do not find yourself needing to do so. Leaving the ARGB unplugged from the motherboard headers allows you to use the button on the case. This case is a great option for those using a basic AIO for the CPU or air cooling. What Can Be Improved: The rear I/O panel 140mm fan is not RGB like the rest. That is silly and unfortunate. The space above the motherboard and behind the motherboard tray needs to be greater. Making the case 1.5 to 2.0 inches taller and about an 1.0 inch or so wider would remarkably improve the usefulness to a broader audience. Above the motherboard it only has enough room for thin radiators and push fans. No way you can install fat radiators and push/pull. That sucks, but I understand "normal" is their target market and gamerboy AIOs is what 99% of their customers are going to be installing. So, since I am using a gamerboy AIO for this application it's OK. It would NOT be OK with a custom loop. There is not enough space for a custom loop to be accommodated comfortably. Behind the motherboard tray it would be nice to have an extra 25-30mm of space. I got the cable management done in a way that is aesthetically acceptable without a bulge in the side panel, but man it sure was tight. My PSU is an RM1200x SHIFT and there is barely enough space for the modular cables. ... show more

Big and has lots of airflow
Style: Air 903 MAX Black Color: Black
Great case, very roomey. The included pre installed fans are nice and allow for good air flow. I like that you can take the front off for cleaning.

Very premium case for the price, easy for a newcomer to build with
Style: Air 903 MAX Black Color: Black
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

Looks great, works greater
Style: Air 903 MAX Black Color: Black
I really love this case. It is large enough to store all the basic components you'd need for a computer including my rather large graphics card and extra HDD. It comes with all the screws needed along with mini zip ties to help with wire management and even had spots to attach those zip ties to so the wires wont go anywhere. The case looks very nice and sleek. The included rgb fans look great and work well. I've never had any issues with overheating and i have it up against a wall in the back. The integrated rgb controller let me attach my cpu air cooler with rgb function so all fan lights are in sync with each other and can be switched with just one button on the top of the case. The quick off removeable mesh screen on the top and dust screen on the front come off fast and easy to make cleaning it simple. Overal this has been a great case an id recommend it. ... show more

Love this case. Fits my 7900 XTX and 420mm Radiator. Idk about other brands but it fits a Corsair H170I Capellix RGB ELITE XT. Keeps my 5900X overclocked CPU nice and chill. Under 50c in gaming and 64c in encoding. 67c in prime 95. If you have or want a 420mm radiator to match the 140mm fans in the case, buy this case. Fits everything, keep everything nice and chill, looks amazing, and soooooo easy to build in. This is by far the best PC case for under $80. Nothing can match it. Buy it. Despite what others said, they may be right for their case they received, but mine showed NO damage anywhere upon inspection. ... show more
