well the only time id move my computer is to open it up to make more upgrades. but will heat issues be a problem if i were to have my new hdd just lie on the bottom of the case??
i wouldnt say the duct is a bad thing. it helps to kepp the air flowing to where it is needed. uder it there should be a heatsink on the processor and a fan on the back of ur case pulling air out thriugh the back past the heatsink
