Best bang for the buck case I have ever used. Cavernous internals make it a breeze to work in.

looks amazing, good price point. could use for being about 3 inches taller so i can fit a 2-way SLI without cramming the second GPU against the case fans on the bottom

My first impressions with the InWin 303 were jaw dropping. It's a shockingly beautiful case. I have watched plenty of video reviews on many different cases with tempered glass and never realized just how little justice a camera does for them. The Tempered panel makes everything look so sharp and clear. It adds depth and reflection that you just can't get with Acrylic windows. That being said, there was some minor imperfections with my InWin 303. The inside was not evenly painted and there is missing spots where the finish looks dull or untouched from paint. This wasn't enough to send the case back as it's barely noticeable with the panel off and impossible to notice with the panel on. I'll call it a minor annoyance if anything.

a little modding would make this case A-Ok

Pretty case but not much room.

Good case, a bit cramped when water cooling

Easy to build in. The side panel window looks great.

Lovely tower which is nearly perfect at this size.

140mm top fan mounts, clear/rgb front lighting, and an extra 10mm clearance at the bottom of the case would make this an auto pick in every build.

As is stands, it's fiddly with an ATX motherboard and bottom mounted fans/radiator.

Looks lovely though, I'd buy it again (with a M-ATX mobo).
