I have this case for my LAN party rig, love it. I fit 5 140 mm fans and 1 120mm on it, great airflow. I have a 3600, with a 5600 XT and 2 SSD's all mounted in it:

I recently built a PC with "leftover" parts and bought this case. The dust filters are going to help a lot because I have a dog that sheds a lot and this PC is sitting in the living room, for multiplayer party games.

Build: Ryzen 3 3100, 32GB DDR4 RAM 2400mhz,Gigabyte B450 Aorus M Motherboard, 120gb SATA SSD and 1TB HDD.

And here's the crazy part: SAPPHIRE NITRO Radeon R9 Fury

That GPU is huge yet I had enough space to install it, and have two fans installed in the front of the case. Thermals aren't too bad but I'm also not going to push it too much. I plan on downsizing to a GTX 1060 when I upgrade to the new RTX 3000 series.

I have this case, and I just ordered a new one to replace it. It runs hot, the airflow isn't great because of the ventilation hole sizing and spacing. Even with an AIO the CPU runs significantly warmer than it should. The case is perforated, but there's more metal than opening, so it restricts flow.

Several YouTube reviews mention these issues, and the only solution seems to be cutting giant holes in it where the fans are, or drilling larger holes with a step bit.

Paul's Hardware:

You can search for the case on YouTube and you'll find plenty of others.

The GN review is the Q500L, but the main difference between the two is the power supply placement. Other than that it's basically the same case and the airflow issues still apply.

For a pure budget build, with components that aren't going to run super hot, it's probably fine if you add a couple extra fans. But if you're overclocking or doing anything else that would push the thermals, you should look for another case.

Is it compatible with 1440p 144hz?
Basically the same thing as "no hdmi".


But if you really are not trolling us; then yes to your question.

Just purchased this yesterday at micro center for $44. Used it for a simple build.

No gpu everything fit smoothly.

Added three fans plus the one pre installed.

Case feels flimsy without panels.

Front panel feels flimsy when plugging in flash drives but for the price you really can't beat it.

Wow. This case was $150 on Amazon during the pc component shortage too. Glad it's back down to a decent price. Built a system for a coworker and the cable management isn't too bad having for having no psu basement/shroud. Those magnetic filters are really are sharp, watch out for those and take them out while building.

In for another one 👍

Just got mine today. The only problem was the there wasn't a UPC label on the box or inside. The rebate tells you that you must tape the original UPC label on the form and mail it in. Amazon agreed to send me a new one, but lets see if there's a UPC code on that. The only bar codes I found were for the shipping from Cooler Master to Amazon. Nothing else.
