I know this is CAG but really - note price is for each unit item, not if it says 2 and you think it's that price.
All the computer equipment that isn't new or sealed has been tested, cleaned, or RMA'd to get factory set condition.
One of the best motherboards I ever owned is the Z97 Machine 1.0 made by L337 Battle Ready. That vendor doesn't exist anymore but wow the BIOS is incredible and it overclocked my 4770K CPU all the way to 5 GHz all cores. Well with the times the 8th gen i5-6600K walked circles around it even at 5 GHz so it was time to move on.
