I'd like to consolidate these 8 machines into a single virtual install to free up rack space and stop blowing needless carbon up the chimney. My thought is to deploy something like a maxed out HP DL380.

I want to have a number of Win XP VMs and associate each one with one of the graphics card heads and one of the keyboard+mouse pairs so the user thinks each virtual system is a real PC.

Normally you would graphically access virtual machines across the
network with VNC or RDP, using a normal PC or a low power thin client.
I'm not sure your suggestion is a well trodden path, although you might
like to google for PC sharing.

How about a 'terminal services' set-up? Essentially one server that
allows multiple graphical logins over the network. Proprietary
solutions may allow high bandwidth graphics, which sounds like what you
were asking for.

DL380s do work well - we use them for virtualisation, although for
servers with text consoles, no graphics involved. I would be tempted to
stay with standalone PCs if they're for intensive graphical apps. How
about looking at your OS' standby modes, wake on LAN and other power
saving features? Just switching them off at the end of each day will
save huge amounts of power.
