Thank Donk for the unlocker, very easy to use and Ken73 and Daft for the simple tutorial on page 18. I was able to get Mac ML set up with the instructions provided.
I installed this on my home/test box running ESXi 5.1.
Motherboard: Asrock z77 Pro3
Chip: i5 3470
Ram: 2x8gb Cosair DDR3
I was able to mount the VMWare Tool straight from the vSphere client and install it very easily.
I installed OS X Server, and going to be playing around with a few of the services.
