Hi all. I'm a long-time lurker and first-time poster. I've been dual boxing for about a year and I'm planning to move up to a five box setup in the near future.

I'm wondering about using 1U rack-mount servers as slave boxes to save space and conserve power. Specifically, I'm considering this server.
.
Of course I'll need to install an OS get a better PCI graphics card in there; I'm looking at XP and a 256m PCI GeForce 6200 at the moment. With these upgrades, can anyone see any reason this wouldn't work? Would these boxes be robust enough to run two instances of WOW with the 256m 6200? Would it be worth the extra $15 per box to get a 512m PCI card?

Thanks to the whole community for a lot of great information -- I don't think I would have considered trying the move to 5 boxes without having such a good resource at hand! (So if my wife complains, I'm sending her to you guys...)
