All I want is a nice tool-less case that is easy to work on, and no sharp edges inside to cut my knobby hands on. The case will hide behind my 27" monitor, so I really don't care what it looks like.
Very happy with my wife's case (In Win "Alpha", white with pretty vector art plants on it, and lets not forget the sequins

). Bought it on sale 4 years ago and the 3 times I have had to open it up (routine cleanings, and a recent HDD failure) I have always been surprised at how easy it was to work on. Sadly I was not able to find the non-girley one a few years later when my case finally died in an unfortunate lan party incident; but the cheap $40 case I found (a thermaltake) is simple, black, and has plenty of space for HDDs and fans which is all I need
