In this video, I will take a look at a Lenovo ThinkCentre M91p. During the video, I will completely disassemble and reassemble the device. And upgrade the RAM, SSD and add an AMD Radeon HD7770 as video card. Once everything is back together, I'll do some benchmarking and see how gaming goes on this machine, by playing Need for Speed Most Wanted, Far Cry 4 and GTA V.
