between those two, get the aopen one. it has the nforce 2 chipset, whereas the soyo has the via chipset. the nforce 2 is much better. my old motherboard is via and i have had problems with compatability. i had a soundblaster live 5.1 and it would not work right with that chipset. they release patches and fixes for it but none of them worked for some reason. so yeah, the aopen one is cheaper, and it looks to be better from what i can tell. it'd be best to wait for someone elses opinion though.
