Yeah I think now Asus has one too... called the "supercomputer" or something...
I'm not exactly sure what people are going to do with 35535 PCI-e x16 slots, and why this is cool, but whatev.
It would've been much cooler if they brought a dual-processor server motherboard to the "desktop" arena instead imo... but maybe there's engineering limitations to the "desktop class" sockets which make it difficult to do so.
