How would you outfit a Photoworks rendering workstation?

I'm curious what hardware people would choose if you were purposely building a workstation for rendering in Photoworks.
We typically buy HP or Dell workstations outfitted to our specifications for Operating System, video cards, RAM and hard drives and processors.
Does anyone have any great advice on these components as specifically meant for maximum Photoworks productivity?
Keeping in mind the new functionality in SolidWorks 2008, what would you recommend for the above mentioned components, including OS.
Thanks for the input!

I'd go with as many cores as possible (a quad core is nice), plenty of RAM (4 gigs for a 32 bit machine, more for a 64 bit) and an approved video card for SW 2008 since Realview and PW are now integrated.

Reasonable cost:
Dell 390 or HP xw4400 Core2 Extreme QX6700 2.66GHz Quad Core 4GB RAM Dual SATA Drives Quadro FX1500 WinXP 64bit
Cost Not So Impt
Dell 490 or HP xw8400 1-2 Xeon x5355 or 5365 2.6 or 3GHz Quad Core 8GB RAM (4x2GB) 2-3 10k RAM SATA Drives Quadro FX3500 WinXP 64bit
If you are in a hurry, check out Dell's Outlet. There are some great deals there right now. If you must get new, negotiate on price.
If not in a hurry, wait a month. HP has announced new systems based on faster Core2 Duo CPUs (6x50 Series) that are much less expensive than current line. Dell can't be far behind. (You can get the new CPUs from XI and other "second tier" suppliers now.) Should be shipping soon.
Even faster systems will be shipping after 1st of year, but you can't wait forever.
