Our community has rated this post as helpful. If you agree, why not thank rod4400

I have one of these. For the price, it's okay, but be aware that:
- the transparent plastic side panel will become scratched almost immediately
- if you have the case anywhere where you can bump into it/brush it with your leg while sitting, you'll find that the magnetic panels slip around very easily and you'll need to line them up a lot
- the case in general is made of very thin sheet metal (if you're used to old-school beefy ATX cases like I was you'll be surprised).

In general, it feels cheap because it is cheap, so as long as you go into it with that understanding you'll be satisfied.

I had terrible, terrible thermal issues with this case (air cooling, didn't do AIO). Look up Gamers Nexus review of this case and you'll find out why. If you want to use this case for basic computing it's fine and it's a nice size, but if you plan to do ANY gaming, I'd look elsewhere. I literally had to take the side panel off any time I wanted to game so my PC didn't overheat. Don't make the same mistake I did. I ended up having to replace my case entirely and now I have way better thermals.

Wasn't that the Q500L?

Looks like you're correct. But from my experience I had the same issues with the Q300L.

Built 5 PCs with this case. It's as cheap as described, but it's great VFM at $46.

Just remove the magnetic filters and you're good to go. The front takes a 280mm AIO and a 12 inch GPU which is ample for a compact gaming build.

I'd recommend this case to anyone looking for a small build that's easy to lug around.

Its pretty well ventilated I have no issues with it, also printing a carrying handle for the top is an option, although it is just held by the sheet metal with m3 screws
