I don't know anything about Rosewill power supplies, but your PSU is one thing to never overlook. Reliability should be the main thing to look for. Not just in how long it lasts but its efficiency and ability to prevent "dirty power".
Just a few extra bucks and you could find a harddrive with a 16mb buffer instead of the 8mb. I recently bought a seagate 320gb for only $95, and that includes shipping!
$40 can get you a decent DVD/CD combo. If you really want a sata cdrom (which I dont blame you for wanting) then it might be harder to find a dvd drive.
I've never used an Abit board before. I currently have an Asus and its never given me a problem and it has a great Bios.
