I personally prefer the HAF 932 or 922 over Antec 1200 or 902 for cable management features as well as superior design.
However I would have to recommend a K62 by Lancool.
Great cooling, far better design, and really aesthetically pleasing.
If your seriously about spending $300+ you can get the Coolermaster Cosmos 1000.
For heat sink on an i7... Dark knight will do fine, or a core contact freezer (will require a bracket to be purchased separately.
