Vinny, I've been considering a tower as well, and I've narrowed it down to a few.
I like this guy's pro-style tower. The most inexpensive I've found, and several folks on this board have good things to say about them.
www.diywake.com Everyone also highly recommends the Moster Towers. I think they are about $1200? Not sure, but I think this is the site.
www.monstertowers.com Also, heard good stuff about this tower, it seems highly recommended for $895.
