Yeah, the nForce2 chipset mainboards are the go. Give that board you picked a big miss if you build a PC. Via chipset users seem to have probs.
Here, the Asus boards always cost more, and I have found some excellent alternatives that offer all the PRO features for less than the Asus base m/boards cost.
Soltek produce an excellent budget nForce2 board, the SL-75FRN2, as well as a few more variants.
Gigabyte also produce nice boards.
MSI make a good looking nForce2 board, but I have heard one guy screaming about them, because it didnt work right, but another freind had a similar prob with a new Asus board, so it's probly luck of the draw. There are obviusly duds making it onto the market.
I can recommend Seagate drives, the last cheap one I bought was faster than the one I got before with 8mb cache ram, and I paid a lot for the cache model.

Also, the XP2600+ cpu isn't all that expensive compared to the whole rig, and a fast cpu will offer a smooth running machine, less prone to hang ups. So, I wouldn't go for a el cheapo CPU unless budget is a real contraint.
That CPU is probly gonna run warm, so make sure you have good ventilation in the case (fans).
