So lately my thermaltake armor case has been ****ing me off due to the fact that i have this huge window in the side and not a single fan. I have a pretty nice setup and everything is well cooled running all swiftech water cooling, 1 rear 120mm fan, 1 rear 90mm fan, one front 120mm fan one top 120mm fan one 80mm fan cooling my hard drives by my psu and my psu has 2 80s... Would it be a bad idea to drill a 220mm hole into my window and put a big sidefan in? if i did so would i want to blow it in or out? thanks
