Z68 also supports it, but this should be enabled by motherboard producer (not all of them do).

A little late but... In my experience:

Q35
http://ark.intel.com/products/31918/Int ... Controller
HP/COMPAQ DC7700 CMT and DC7800 CMT - works with ESXi 5.5
DELL OPTIPLEX 755 - works with ESXi 5.5

Any Intel VPRO compliant vendor based PC should do. (But I could be wrong here...)

Make sure you get the correct CPU to support VT-D also

Flash your bios cpu support microcode, then bios and AMT/ME firmware if it has this support.

The AMT/ME subsystem can let you remote power on/power off these VPRO machines via a SMB web interface (that you configure) which is very handy and most general boards don't contain this, also newer AMT/ME bios' contain DASH/DMTF support (which can allow for remote video management if you use the onboard video and onboard network)

Last thing, if the board has VT-D support and you enable/disable the functionality, after saving the bios setting and rebooting make sure you unplug the system power for at least 5 minutes - some systems will disallow certain changes without full power drop.
