Thanks for the help.
I guess I should've said a micro atx board with oc potential and the latest chipsets. I couldn't find any with the sis 655. Aopen seems to have some for all other chipsets, but noone sells them.
Newegg's search/filter didn't do a very good job, so I manually sorted through the boards. I found the MSI 845GEM which seems to be the winner. There was a liteon, but I couldn't find much information on it. There were a bunch of intel boards, but they were using older chips and were quite pricy and lacked some features.
The MSI looks to have the most control. With its fuzzy logic software, you can supposedly control the fsb and voltage through windows. This may come in handy if I need to undervolt or plan to overclock.
