I have an Antec 900 Gamer case. Its sweet 4 fans cool my system fine the problem is that it acumulates dust at an alarming rate. Is ther a solution to this? Also i have a small USB Hover that i use to remove dust from the PCBs and other fans and cards is it safe to use this device while the pc is running? I have had no problems so far but im worried i may damage the PCBs or Cards by static discharge? The USB hover does have a small rubber hose, does this allimanate possibe damage by static?
