I'm not spending $250 on a caseAlthough it lacks any LEDs, I would recommended considering the Silverstone FT02; it quite solid, got a nice window and has great thermals. One thing I will say, however, is that the window is on the 'right' side of the case whereas it seems most cases featuring windows place them on the 'left' side of the case.
A great case though.
Check out the Cooler Master CM690 II. It's got great reviews (both professional and on retail sites). You can pick up a side panel with a window.
