Gaming on Dell Optiplex 960

Pickup up an old Optiplex 960 and trying to upgrade into a gaming PC. This is to show that if you happen to have the same model, this is what you might be able to make out of it. The main limitation is the Motherboard is BTX size which makes it hard to find suitable graphics card which will not interfere with the cooler. Another issue shown is the motherboard's I/O are also blocking it when using 2 slot card as the fans are facing upwards instead of downwards. Apologize for the poor quality video. I do not have a good camera and this was recorded on an old Samsung phone.
