This is the case I decided on. Good size (full tower is too much for me) good looks, reasonable cooling, a window, and good price. I would have picked the super lanboy, but I think it is ugly as all hell.
My build was about 2500 (I realize this is much more than you are looking to spend, but you might find some of the part selections helpful, I did an uncanny amount of research and I have been buggin this forum for a while now), so here is my build http://www.techist.com/showthread.php?s=&threadid=69274
Good luck!
EDIT: You stand to save alot of money by ordering from monarchcomputers.com if you live in CA, as they do not charge us tax
