haf ftw!
Makes sliding harddrives in and out alot eaiser.
question do you really need a full size case? Plan on living inside of it after the bank goes bankrupt?
Still Antec can push more air...is far more customizable but if you want to go water cooling the cool master makes it easier to do so.
Might help if you explain what you want and what your using...a smaller Antec 900 could suit your needs and can be SHIPPED free right now with newegg.

Around Christmas time (after Thanksgiving until Christmas), newegg usually has killer deals on everything including enclosures. Last year, they sold the CM Cosmos for under $100 shipped after MIR. Continue to keep an eye on things and you'll find what you want at the right price.
