i have the shuttle an35-(n) ultra motherboard, it looks good, works well, and no problems yet, it has onboard sound, ethernet, usb2.0, and supports three sticks of ram, a pair can be a set of dual channel. it's about $50 and the processor about $80? then you come in well below, at $130
that motherboard is for almost all general activities and is easily upgraded - five PCI slots, and one AGP i would recommend!
~~::EdIt::~~ ehhh well i could be wrong in price on the motherboard, when i bought it, the price was about $70 i believe and figured the price would go down, apparently it hasnt, here's a link to it:
