I will give you a top 5 if you want functionality over design i'd go with
Haf -x 942 *not 922 or 932 as their have been terrible problems with top panel connectors being flipped 180 degrees*

Cooler master Storm Sniper- this is the case i got, and i love all the features of it, it is very build friendly, excelent airflow, silent operation, anti vibration 3.5" drive tooless mounting system, rubber grommets for PSU anti vibration, Great cable management as well with bayed out side panel, can fit the largest Video card on market as well, and a cpu backplate for aftermarket cooling. I also find the looks to be better than ever case i listed or seen in this post.
