NVIDIA GeForce GT 120 graphics card pulled from a 2009 Mac Pro (a1289 EMC 2314). This machine powered on initially and tried to boot - clear video with no issues. But, then it woudln't power on.
So, I've parted the machine (it had a damaged base - bent) so it wasn't worth playing with further.
I've used these GT 120 boards in PC's and they work nicely with decent performancem (in Windows 10). They will also work in a Mac Pro if you need a new (or were missing the) graphics card.
Thanks for looking and offerding. Email me with any questions you might have.
