I have a ssd in the tower so that doesn't stop any airflow, besdies that there's no cd rom drives or anything so the fans in the front which have air filters too all get right to everything, and my second normal spinny hard drive is plugged into the top of the tower it's not even in the tower lol, and all my wires I put them behind the motherboard there's no wires to stop airflow either it looks like it was pre-built except better than pre-built because I spent months re-wiring it to get it 100% perfect after wire heat shrinkage/longage etc that shit too, I own your fucking life bro
