I would attribute that to the poster not knowing a whole heck of a lot when he bought his hardware, or about the availability of various fixes for the issues he's having. There is a vast amount of information out there. The DVD not working is of course due to him setting his BIOS exclusively to SATA instead of compatibility mode. The audio, if its even close to a new motherboard, should be able to be solved quite easily with http://code.google.com/p/voodoohda/ or HDAEnabler. Some of the stuff he does is unnecessary. A lot of newbie mistakes. The only thing interesting is that it's an i7.

ETA: Written on my faster-than-a-mac-pro-and-only-cost-800-dollars-hackintosh.

Fixed since then.
