Fans!

Okay, so to cool the PC, I need fans. I thought about having three fans on either panel, 2 at the bottom the pull cool air in, and one at the top to push hot air out. I bought the fan grills of eBay (one of which, differs to the others) and I bought all 6 translucent green, fast-ish fans from a local computing shop, they were the cheapest I could find.
