Used gaming pc 2tb storage easily runs games

I have been using the pc for almost a year now and have never experienced a issue. It has ran every game I have tried at full settings and a average FPS of 120. However even though theres no performance affecting issues I have never been able to get the LED’s to work on it, i dont know if its fixable or not iv just never tried. All the fans where fairly cheap except for the front three antec fans which they all work perfectly fine and keep the pc like a cooler because I added alot of fans.
