Basically anything with a ULi or Nvidia chipset is a good choice, and you just need to shop for features and stick with a good quality manufacturer. I've also seen nothing but good things about the more recent ATI-based boards, but have no personal experience with them.
Avoid VIA like the plague upon this earth that they unquestionably are.
That said... they've made massive strides in recent years, but I still despise them.
So far as board manufacturers are concerned I tend to stay with ASUS, Soyo, Gigabyte, MSI, and Chaintech. Beyond that it's really a question of individual feature-set and personal preference anymore.
A side note: I'd warn against Western Digital harddrives, and Hitachi/IBM as well. Stick with Seagate and Maxtor for the most part. The price differential isn't that great, and I've had nothing but bad experiences with WD drives -- 5 out of 5 dead, 3 of those within 2 years, 1 within 2 months.
