Akasa Eclipse-62 Aluminum Case - Great case but ugly plastic front
Antec P180 Advanced Super Midi Tower Case - Good, but a few too many little problems
Coolermaster Wave Master - Cooling isnt brilliant, uses 80mm fans so fairly loud (stock anyway)
CoolerMaster Praetorian - I hope you mean the ATC version

(not the newest one) absolutely brilliant but hard to get hold of.
Also seems that any of the Thermaltake cases are good for high performance/gaming systems. - Some are ok, I don't think any could be considered "the best" case though
