ESXi 5.0 White-box
Am going to try EVC for my Core2Quad box with my new i7 box.
Here are the specifications of my new whitebox if you are interested in building one. Note the chipset of the mainboard which is the crucial part whether ESXi can be installed on it. So far I discover P67 chipset seems to be working for all models. So I bought the Deluxe series as the Evo series was out of supply.
I bought my Intel Dual Port from dealextreme. It took very long to shipped and its not cheap as they are server NICs.
