I just bought the Antec NeoHE550. It's modular (love my new uncluttered case!!) -- runs quiet.. has dedicated rail, runs cool.. has connectors for SLI.. has the 20+4 pin setup to match all boards. Just a beauty -- spent about $130 Canadian.. could not be happiers. However if you are using an Asus board everyone was telling me to stay away till Asus fixes the issue.
