For a friend I build a ESXi4.1 VMware server. A Shuttle SX58J3 with Intel Core i7 950 3 Ghz, 8 Gb memory (4 slots available), 2 PCI-e slots:1 used for video card and 1 for dual port Intel NIC. Problem: onboard NICs not seen by VMware.
This vSphere server is connected to a QNAP TS-559 pro+ storage by iSCSI. Now running 1 Windows 2003 small business server and 2 Windows 2003 servers and 2 Windows XP. System is fast!
Add an other Shuttle and we have a cheap datacenter in a box. Nice to SMB.
