VMware Lab

I am in a dilemma about a PC for a VMware lab. I will run VMware Workstation 9 with 2 - 4 esxi hosts, 2 dcs, 2 vcenters, 2 srm servers, 1 view server, a vloud server and a sql server. Not all at one time. I am thinking about 16 - 32 GB memory, an i7 dual or quad core cpu, and a 2d video card with 2 monitor support.

It would be nice to have a laptop for this, but am leaning towards a desktop. I have no idea as far as a motherboard, video card, or case. Any and all help is appreciated. I do have an ASUS G74SX with 16GB memory, but am having issues with the Nvidia card and drivers.

Thanks,
