The only problem I personally have with that case is the orientation of the 3.5" bays. Any more, I prefer them be rotated 90° from the way they are in that case for the simple reason of cable management. I'd rather have them tucked away behind the rear side panel than sticking out over my motherboard.
And before anyone else says it, I am also well aware that beggars cannot be choosers when talking about a $30 case. Otherwise, that case looks very sexy and if it weren't for a server, I'd probably deal with the cage orientation and snag one.
Yeah, I prefer the other orientation, too, on those 3.5" bays.
Slightly off-topic, I'm waiting for some PC Case Maker to figure out they need to have a SATA backplate on those slide mounts so all you do is mount your 3.5" or 2.5" drive in the tray, slide it in, and "snick" pop it into SATA connectors fixed in the cage. The cable end would pop out by the motherboard.
Of course, with m.2 and all the other new crazy options...SATA is becoming obsolete.
I'm keeping my eye on this thread for a decent mid-tower that's liquid-cooling friendly. Yeah, anything that mounts the PSU at the top, or has old-school front-to-back 3.5" drive bays will not do. Luckily, that project is at least a few months off. Just picked up a Thermaltake V71 at NewEgg for $90AR for my "premium" system build this October - then I'll have a few things to spare to rebuild a system using more budget components. For that build, I'm replacing an HTPC case that didn't work out very well (do they ever?), but sound dampening and high-performance air flow isn't as much of a requirement.
