This is my Dell Optiplex 790 which I transferred into a Masterbox Q300L. It's been difficult but I have transfered every part of the Optiplex 790 into another case with it functioning as it should except that you can't use the front I/O build into the case or the front I/O of the Optiplex. I also plastidipped the motherboard white. Specs - i5 2400 3.1ghz - GTX 1050 TI - 10gb of ddr3 1333mhz RAM - 710gb of hdd storage - 450 watt psu.
