I would highly recommend the Asus P4C800-E Deluxe motherboard with a good set of OCZ PC-4000 Gold or higher RAM, then throw an Intel 2.4C P4 processor in that baby and let her rip!
The only other thing I would say is, don't try to save a few bucks on where you purchase your product. Go through newegg as they have such a high rate of sales your almost guaranteed to getting the latest revisions of all the hardware you want to purchase, namely motherboard and RAM. I can't tell you how many horror stories I see with people save a buck or two here in there but ending up going through a supplier that gives them old revisions or equipment that has previously been used!!
I purchased all of my equipment, except for a few items that were specialized, through newegg, they were phenominal in their getting this equipment out to me and they were in perfect condition. Save yourself the trouble and get your stuff from one source, and if it's going to be online then go with these guys, you won't be sorry.
I would say the same thing about OCZ. Their support is outright fantastic!! I had an initial problem with a set of OCZ RAM not passing MemTest-86 and they sent me two other sets to try quickly. Not only did they fix my problem but they essentially gave me sticks that were rated higher than my original purchase (Speed).
If you decide not to go with Asus (although I don't know why you wouldn't) then I would suggest the Abit IC7-G but not the MAX3. There are still a number of issues people are having with their newer Max3 so I'd stay away from it for now until they get it cleared up, but the IC7-G is solid and if you can do without the newer features of the P4C800-E Deluxe and the Max3, it's a good choice.
If your not planning to overclock it then, well, take your pick. Asus, Abit, Intel, all make good boards.
