That's not necessarily true. The Chieftec Dragon is generally $100 for the mid-tower, yes, but one can find it for $50 off eBay (which is what I'm going to do probably), and occasionally they have it on sale in some places. I recall, for example, that Tiger Direct once had it for as low as $27 (clearance) - but yeah, not with LED fans etc. (though they're cheap, and it wouldn't be hard to install).
http://www.xoxide.com/allcases.html I'm particularly a fan of the appearance of the X-viper, and X-turbine is pretty nice looking too IMO. Still though, I think the best thing would be to get a Dragon off eBay (very light, nice looking IMO, a hell of a lot of features: requires pretty much no tools for installing/changing out hardware, except maybe the mobo, etc.), and spend the other $20 getting some LED fans and a CC or something.
