That case isn't very cable management friendly

so really your only option is a butt load of cable/zip ties or using the left over tray holes and two zip ties by joining them together to make a slightly longer one by passing one end through the hole from the backside of the tray and the other through the front then partially join the two behind the tray then bunch the cables together and join the front side ends together



and try using some 1x 4 pin molex to 2x SATA power cables that should get rid of atleast one cable

or use a dremel and get cutting and make some cable holes in the mobo tray
