Building a team of WoW computers, opinions?

I'm going to get back into WoW multiboxing and figured why not give hardware boxing a try. So, I'm building four cheap $500 computers for my alts and use my beast pc for my main. I'll have two 22" for the main pc and 1 19" for each of the alts. My question though is does Keyclone work for multiple computers to pass the keystrokes or no? If it doesn't, what could I use to control all my accounts like I would with Keyclone on one PC. I know about synergy, which I'll have that to use one keyboard/mouse for the computers, but does that work inside of WoW to?

Here's the build list for the 4 PCs that will run my alts. Anyone know of parts I could substitute to bring the price down?

you may want to check out microcenter.com, i recently built my very first computer and went to the store and they were helpful and i built a nice computer for about $450 after rebates

that looks pretty solid.. will a 7200GS be enough to run WOW.. and do it well. also why get a nice e8400, and a crappy GPU.

maybe spend a little more and get a 8600GT, or a 9500GT. and get a slightly older CPU. as you don't need a E8400 do you. something slower would work, and you could always overclock.
