From my soon to be published Blog about building a Home VMware system with ESXi 4 at http://www.grennan.com
This is the "Desktop version" of the X8SAX main board.
* SUPERMICRO MBD-X8SAX-O LGA 1366 Intel X58 ATX Intel Core i7 Server Motherboard ($279.00)
* Intel i7 CPU
* 12 Gig of memory - Crucial 6GB (3 x 2GB) 240-Pin DDR3 SDRAM ECC Unbuffered DDR3 1333 Triple Channel Kit
I purchased these form Egghead. Everthing as work perfectly out of the box without any modification. I am booting from USB thumb drive connected directly to the main board.
For disk redundancy I am using software RAID across multiple data stores.
