Mac Pro "Quad Core" 2.66 (Original) 2006 14RAM For Refurb/custom Lot B. Condition is Used, This had been sat in my office for many years, I’m not sure if it works or not as I dont have a HD to try it with. It’s very dusty inside. Once plugged in it makes all the right noises ans the lights come on, I might not be right but I might have put and additional cd drive a few years ago. This is perfect for a custom just or to be taken apart for parts. I cannot tell you what works and what doesn’t. It does not have its box all 4 bays and screws No graphic card inside. It has a high amount of ram this machine takes 32 ram, and has 14 to use. It has power cable.
