sjk007 :
I like RaidMax's PC cases, looks great and lots of space.
Here's one I'm eyeing at the moment:
Raidmax Viper GX

For $90 there are many cases better than the Raidmax Viper. I would look into a case from NZXT, Corsair, Phanteks, or Fractal Design (few good ones off the top of my head). If you want a green theme all you need to do is add some green LED fans or a LED light strip.
