Cooler Master MasterBox Q300L TUF Gaming Alliance Case | $59.99 $29.99 at Amazon (save $30 after rebate)

Used this case a few months ago for a friend's all AMD build. Good value for $30ish, but it's kinda strange:
  • It starts off on the right foot with stylized magnetic mesh (i.e. dust filters) on the front and top of the case, but like you'd expect in this price point ($50 at Microcenter): there's no pre-installed intake fan. There is one pre-installed 120mm exhaust fan.
  • The windowed side panel feels like flimsy plexi-glass (i.e. acrylic), but the panel has a neat "premium" feature that allows you to relocate the USB/audio/power button panel from the front to the top, bottom, or rear of the side panel.
  • There's plentiful cable management channels along the tray, but none of them have rubber grommets. While it does have anchor points for zip-ties, there are only 3 of them and all are along the channels. Could really use at least one directly behind the motherboard tray to tie-down the 4/8-pin CPU aux power as well as top/rear fan cables.
  • Speaking of the rear motherboard tray area, there's ample space to mount a 2.5" storage drive or even a full 3.5" HDD.
  • The 4 expansion bays are all the extremely cheap push-out design. Have to be really careful when removing these as you can bend the remaining thin steel frame.
  • The PSU requires a bracket which serves no apparent purpose but to complicate the installation and potentially block your AC power cable. We used a Seasonic Focus Gold 650W semi-modular power supply, which cleared the bracket, but not without rubbing.
  • There are no clear indicators for mounting front/top fans, just hundreds of stamped out holes, and a few counter sunk screw holes for radiators. This means if you're mounting front/top fans, you'll have to slide the fan around a bit until you find 4 holes that line up.
  • Thermals were fine in our tests (we installed additional 2x 120mm intake fans). Buddy's Ryzen 3700X was idling at 40-50C and when hit with a synthetic load (OCCT) it topped out at 75C (attached HWinfo screencap). This was achieved with the stock Wraith Prism cooler and its pre-applied thermal paste. Didn't get a chance to do any thermal testing on his 5700XT (reference blower design) unfortunately.
  • Max CPU cooler height this case supports is 159mm.
Overall, it's a good-looking serviceable case with a lot of cut corners.

It is a strange, but goodish, case. We've built into a few of them as well and Spartan's review really nails it. It's good, but you have like something a little different to appreciate it.
