I'm trying to build a computer that's powerful enough for me to run a couple copies of server 2003, 2x exchange 2007, and some clients. Any recommendations on what would get me the most for my money? I'd want at least 4GB of ram but I'm just not sure about the best mobo / CPU combo, or if it should be dual CPU or not. My budget is about $1000 for the mobo and CPU(s).
