Originally a 2006 "MacPro1,1" 825-6874-A model. I upgraded it many years ago with two Xeon quad-core X5355 2.66 GHz CPUs. It is now a twin-CPU, eight-core machine. OS X identifies it as a "MacPro2,1" model.

"About This Mac" reports the following

Model Name:	Mac Pro
Model Identifier:	MacPro2,1
Processor Name:	Quad-Core Intel Xeon
Processor Speed:	2.66 GHz
Number Of Processors:	2
Total Number Of Cores:	8
L2 Cache (per processor):	8 MB
Memory:	12 GB
Bus Speed:	1.33 GHz
Boot ROM Version:	MP21.007F.B06
SMC Version (system):	1.7f10
Serial Number (system):	RM7290VEUQ2
Hardware UUID: 00000000-0000-1000-8000-0017F207EB48

  • Original GeForce 7300 GT video card
  • DVD drive
  • 12 GB RAM
  • Airport wireless module installed
  • Bluetooth module installed
  • 4 empty hard drive sleds

No hard drives, no keyboard, no mouse

Box (but not the original box).

The highest version of OS X that will run with the 7300 GT video card is 10.6.8. It is possible to trick a better version of OS X into installing with a better video card and some knowledge from the Internet. This is an Apple-imposed limitation, not a hardware limitation.

Local pickup in London, Ontario or will ship to any Canadian address at buyer's expense. Reply with your postal code for a shipping cost.

Todd, I can confirm that this box can run Yosemite. I've done it myself.
