I have a friend selling his old 2006 Mac Pro 1,1 for $1000. It's a single quad CPU @ 2.66GHz with 2GB (2x1GB) RAM. NVIDIA 7300 GT, Superdrive and 320GB HDD. No wireless. I guess I have two questions really, first is this even good value? And secondly is it worth bothering getting a machine this old? As far as I know I could upgrade the graphics to the new Radeon 5870 for $450 and have maybe get an Apple store to install AirPort and Bluetooth for $50 and do a ram upgrade to maybe 8GB for $300. Maybe even go totally crazy with a second CPU tray and CPU upgrade. What do you think, good or bad cost efficiency? Would it make more sense to save up and just get a base 2010 model? How about longevity? Think this machine would be able to handle modern software for another 2-4 years?
