The main advantage of Intel mobos is stablilty. They are VERY stable. Disadvantages are: performance, and lack of overclocking options. It's your choice. First off, you're gonna need a P4 power supply. If you've got cash, go with the Lian-Li PC70. Aluminum. Look also at the Antec 1040B, which is quite large, and black. Good Luck.
P.S. Why waste your money on a P4???
