If I don't sell my 4,1 2009 Mac Pro 2.66 GHz Quad-Core Intel Xeon with 24 GB 1066 MHz DDR3 ECC memory, ATI Radeon HD 4870 512 MB GPU, and Intel 160GB SSD, what can I use it for? Or do with it? I am planning on getting the nMP when it comes out. I could buy OS X Server and host my own website? Is it worth it from a cost/price standpoint? Sounds like it would be fun though.
