I have a budget of around $100-$150 for a new case. Right now, my personal favorite is the Azza Hurrican 2000. I like the extra fan blowing on the back plate.
That being said, what I really want is a great case for air cooling (Gigabyte windforce coolers in sli and a noctua NH-u14s Cpu cooler), but will also be great for expanding into liquid cooling down the road as I get more cash, Christmases, etc. My current case doesn't offer anything like that. I'm hoping to get 3-5 years of expansion out of my next case, eventually going liquid on the cpu and the graphics. I live in the US so I can't imagine having too many shipping problems. Let me know what you guys think from experience, and let me know if that back plate fan is really worth it since most cases don't seem to have that available.
(P.S. If any of you have the Asus Crosshair V Formula-Z, check the 8350 overclocking thread, I left a question there. =D)
