from completed build Plain Jane

I was a little apprehensive about this case - it's not very new, I thought it'd be massive, and it's not very glamorous. Turns out, I didn't want glamorous, it doesn't matter that it isn't a newer design, and it's not super massive. It's exactly what it's billed to be.

I only have two complaints: I wish the bare metal in the case was painted black. I did not make a flashy build, but it just looks soooo much better black.

Second, there is a metal tab to delineate the inside edge of where the PSU should sit. It's just the sheet metal of the case bent up in a small rectangle. In my case, that wasn't bent at all perpendicular to the bottom of the case, so it angled inward; it required using pliers to straighten that before I could get the PSU in. Again, not a big deal.

What others said about half the vents not being filtered is true and strikes me as a bit silly, but I don't think it renders dust control "meaningless." The two main intake fans are filtered. The PSU intake (on the bottom of the case, no less, is filtered. That's pretty important and probably helps cut down on dust quite a bit.

Overall I'm super pleased! Nice and simple looking case that is entirely unoffensive.
