I'm currently amassing some 'tasty gear' for a kick ass PC and I need some advice on proper ventilation. I've got me a clear acrylic case which has five 80mm holes pre-cut in the panels. Looking from the front there's one below the drive bays, a blow hole in the top panel, a hole at the back just below the PSU and two more arranged vertically on the lower left hand side of the left hand panel. Fairly common straightforward stuff. I propose to recut the blow hole to 120mm to accomodate an aluminium fan to which the watercooler radiator will be fixed, venting straight out of the top of the case. The back panel is to have an 80mm fan venting out. The hole in the front is to vent air inwards through an aluminium mesh filter. Feel free to criticise this approach but my real problem is what to do about the two holes in the left hand side panel. Should these vent in-to or out-of the case? CPU will be an XP2800+ and graphics card will be a GeForce FX as soon as they become available, so I'm likely to have some serious heat issues to overcome. For information, the motherboard is an Asus A7V8X Gold, memory is 512 Mb of Corsair XMS DDR3200, hard drive will be a Western Digital Caviar 80GB SE, sound card will be a Videologic Sonic Storm and I've got a Sigma X-Card DVD Decoder, 'cos frankly software players leave me decidedly underwhelmed. I'll be keeping my Plextor 8/4/32A CD Rewriter but I'll more than likely upgrade my Pioneer A04 DVD writer to an A05. The mission is to have a no-compromise games machine that I can still use for regular PC duties, but the emphasis is definitely on games. Internet will be on a seperate machine as I want to keep 'software clutter' to a minimum. Whaddya reckon?
