A shop in the Bay Area called "Central Computers." Once ASUS announced their TR40 motherboard I told him I wanted that, 64GB of RAM, and a 3960 or 3970 when they came in. He called me Friday morning and said, "ok we have it". Since by that time the 3990 had been announced as well I told him to put me down for one of those when they got them as well to replace the 3960.
