The specs on the board look good, but I can't speak to quality. ASRock is known more as a bargain manufacturer than a high quality manufacturer.
The PSU in that combo is good (see this ranking of PSUs
). It's a tier 1, indicating the best quality. However, That case isn't very good. It doesn't have many fans.
I really like the PSU/Case combo: OCZ StealthXStream 700W and HAF 922
for $100 after rebates. The case is one of the best available, and the PSU is very good quality for very cheap (tier 2 on that list I posted). For the price, I don't think you should be looking at any other PSU or case...
