Cooler MasterMasterBox Q300L Micro-ATX Tower with Magnetic Design Dust Filter, Transparent Acrylic Side Panel, Adjustable I/O & Fully Ventilated Airflow, Black (MCB-Q300L-KANN-S00)

This is an absolutely amazing micro-ATX case. It is easy to work in. It looks great. The filters on the bottom, front, and top are easy to wipe off and do a good job keeping things out. The cable management is better than expected for such a small case.The only caveat to all of this, is that this case is not sufficient for modern high end video cards. It will not support a 3 wide and 3 fan GPU. While one could technically fit once inside there is not available space in the opening for it to be inserted.

I needed a smaller case. As I've aged out of the IT industry, my needs have changed. I moved from an old Antec 1200 super tower down to this. I didn't need the big case anymore, since hard drive sizes have gotten so much larger, I didn't need the big RAID arrays to store all of my media. I also moved to a smaller desk.This little guy is a great case for it's size. It's easy enough to work in, has good cable management options, and breathes great. I've only got one fan on it, for exhaust, and a huge, top-end Thermaltake double tower air cooler on my CPU. The CPU never gets over 70c, even running BOINC programs full tilt. There doesn't seem to be a need for more fans, except maybe for looks? The side cover seems to seal well. The vent filters are working well.

Built a few rigs in my time, in lots of cramped and ill thought-out cases. This one is a win. Large open design, lots of cable routing beneath the mobo tray, accommodates lots of fans. I was surprised to get actual tempered glass, as others had reported plexiglass. I've never been a flashy PC guy, so I used some frosted glass window cling on the inside of that panel. The Thermalright Phantom Spirit cooler I used just barely fits at 6.06" tall. I don't think a Peerless Assassin would. Would be cool if they offered a perforated steel replacement panel. The USB 3 ports up front are a huge plus, as this is a VR Rig. The back panel is tidy and clean. The PSU mounts on a bracket, that recesses it about an inch, but I had no issues getting a standard power cable plugged into it. Here's what I crammed in this spare parts/impromptu build:mATX ASRock moboRyzen 5 7600 w/ phantom sprit coolerMSI Mech X2 RX 6700 XT64 g DDR5 5600Corsair 800G PSU(4) Artic 140mm fansThe case is well ventilated and stays cool. The magnetic filter panels are interesting. Not sure how effective they are, but they'll stay in place if the PC is stationary. I have my PC laid on its side, opposite the tempered glass. The panel screws on this side have round rubber feet on them. The feet on the PSU side are rectangular and feel like harder plastic with adhesive rubber pads.The only little gripes I have about the case is that the power led is quite bright. I'll need to dampen it somehow. I'm not sure what purpose the bracket over the card slots serves, unless it's for cosmetic reasons.I'm a fan of mATX & mITX builds, so it will now be hard for me to use or suggest anything else at this price point. Grab one!

Beautiful case. Lots of room for cables, fan, and lights. Great air flow. Built a nice looking pc using this case and I was happy how easy the build process was thanks to this cases many features. Comes withh all the scres you will need, and mounting standoffs for the motherboard, along with a tools to install those standoffs.

Fantastic case for $40. Used it for ~1.5 years, found zero sharp edges, have had zero problems. Light, sturdy, easy cable management, and looks great.

This case does not look particularly sexy. It's not going to elicit a second glance. It doesn't have a particularly amazing build quality. It's light, unassuming, and basic.And I have 3 of them!I think of my pc case as a thing to do a good job of holding pc parts, not as a showcase or trophy display. This thing completely slams. The airflow is amazing and my computer is almost silent because it's so easy to keep cool in this case. Admittedly, I was a little worried when I recently decided to upgrade my GPU to a 6800 xt. If you're going for a 3 fan gpu, you will want to pay attention to its dimensions. But even with that beast crammed into this case, the airflow is still overall amazing. I only have two front fans and an exhaust fan along with my CPU tower cooler.If you don't care about aesthetics, I completely recommend this case.

It's cheap, has decent build quality, easy and enjoyable to build in . Has tempered glass, and not a bad looking case . This case wasn't designed for high TDP hardware . People spend hundreds of dollars on CPU, Motherboard, GPUs, and totally cheap out on a case, then complain about airflow and thermals ....I don't like the fact that it doesn't have a basement, the mesh panels are meh and feel a bit restrictive , I'm also not a fan of the thumb screws on the side panels . It feels like a hassle to get in and out of the case . The included fan is cheap plastic garbage . Invest in higher quality fans .Overall, it's not a terrible case if you have low TDP hardware and you're willing to sacrifice some creature comforts for price . Great for low end budget builds

Works well for everyday use. Sturdy and reliable so far. Happy with this purchase.
