I emailed them back in the summer asking about those same items.
A630 was unavailable and probably would remain so.
BlizzardPPCs were on order from DCE, they expected delivery 2 weeks from when they emailed me (early August?).
3.1 ROMs were in stock.
I didn't ask about motherboards.
Try emailing them. They responded to me pretty quickly. Has your credit card been charged?
