Gratz on the solutions, and welcome back.
My server has way too much crap running on it. SQL 2005, Virtual Server hosting an Apache guest OS (yes, laugh, go ahead!) IIS6, a few websites, my webdev environment, basic Office crap, Dreamweaver, my product I QA here at work, and now - EQEmu w/10 dynamic zones.
Oddly enough, it runs rather well. But it is a P4 3.0 w/2GB RAM on a RAID0. I have plenty o resources, but if I ever get serious about this, I will need to dedicate a few machines to Emu alone. And give Apache a real home.
