Here's what I'm getting:

Intel BLKD975XBX2KR LGA 775 Intel 975X ATX Intel Motherboard
ASUS EN7300GT SILENT/HTD/256M GeForce 7300GT 256MB
Seagate Barracuda 7200.10 ST3320620A 320GB 7200 RPM IDE Ultra ATA100 Hard Drive
SAMSUNG 18X DVD±R DVD Burner Black SATA

The 975XBX2 seems to be the consensus board among everyone here for hardware support. Am I reading it right that an IDE HD and a SATA optical drive are the right choices? I'm planning on using mac.nub and I'm hoping for as little hassle as possible. Any other things I need to know?

Thanks.

Looks fine. There are cheaper boards than the 975xbx that also work great, but you should have no issues

Get your self a Asus P5W DH deluxe its cheaper has way more functions.
and is just as good + it also supports the next generation of intel chips that come next year

and we have a custom tiger iso

yep get that asus p5w dh / gigabyte p35ds3r / leopard success in shown in them.. why u buying the older 975 chipset... get the all solid caps ds3r man... p35 d way to go.
