It looks like a great build, except for two things.
1) I've had bad experiences with Rosewill. So have a lot of people. For the power supply, do yourself a favor and get a Corsair PSU. You'll thank me later.
2) OCZ RAM is great, but again, some people have had problems. I personally haven't, but my general opinion of OCZ is less than awesome. I guess they would work... I personally wouldn't use them.
Side note:
The Phenom Black Edition is nice, a friend of mine has one. If you're going to do any gaming, I recommend the Core 2 Duo over the Phenom line. There have been plenty of tests to prove that the Duo is completely BA and rocks all around. That would mean a new motherboard though, so blah. You didn't state a purpose for this build, so I'm assuming you're going to do some fairly heavy gaming. You'd probably be happier with Intel, but do as your budget dictates. (Core 2 Duo processors overclock like crazy. I got a cheaper model and with no effort got a 60% overclock on air, running 60 degrees C under full load)
