I have a similar build to yours
Intel i5 2500k
Asus p8p67 Pro Motherboard
xfx black edition 750w
Samsung 1tb F3
Silver arrow cpu cooler
I have the NZXT Phantom case, which is very nice so far quite happy with it but like you said theres so many cases out there, best bet is to just find the one you like best.
Also can try going on newegg or any other site that reviews cases to see what catches your eye.
