Socket LGA775 and PCI-E vid card slot will also mean using DDR2 RAM, just so you know. A lot of the mobos have 4 SATA channels and 1 IDE channel (can use 2 devices). So, if you have optical drives too (CD burner, DVD drive, etc.), then that narrows the field down. Maybe look at the Asus P5WD2 Deluxe, I think they have lots of SATA and IDE channels.
