Mac Pro 4,1 5,1 Backplane 820-2337-A OEM Board 2009–2012 w/ WiFi + BT
This is the original Apple Mac Pro backplane board (model 820-2337-A) removed from my own working Mac Pro 4,1 that was flashed and running as a 5,1. The board is clean, no burnt areas or corrosion, and all ports look in good condition.
