OK I am Green. How about a 120mm108 CFM intake @front bottom of full tower, with 2 80mm 42.5 CFM at top blowing out. Another 120 MM 108 CFM side mounted and Ducted to blow on HSF, and yet one more 120 on opposite side of case, under mobo blowing out. The CFM in would equal CFM out factoring the Powersupply fan blowing out. All fans would be Sunon.
Would the noise be so great as to be unbearable? Total cost of fans and guards including shipping is $75.00. 300 watt PSU. I would like the two side mounted fans rheostat controlled. And I suppose I would need a fan bus. I'm scared to use water cooling and the system will have a Celeron 600 cC0 with a Step Thermodynamics (gulp.. sorry, already have it) Kodiac 6180 HSF and "Throttlebody Accelerator Card". Hey, I bought this Step stuff before I found Overclockers.com. Also there's a favorable review of Step on this site.
C'mon Jeff, I know this post has yer hackles up. Be ruthless. Beat me, make me write bad checks! :D

With too many fans blowing toward the same spot, you create turbulence, and sometimes dead spots, defeating the purpose of the fans. You have to figure airflow a little more closely than matching CFM in and out.

Celerons don't run that hot. A huge amount of cooling isn't necessary. I have a Celeron [email protected] in a midtower. One 80mm bottom front blowing in, one 80mm top rear blowing out, PEP66 heatsink with Sunon 23cfm 60mm fan. The case is cut so that case fans blow straight through, and I enlarged slightly the vent holes in the front plastic bezel for better intake. System stays very cool -- CPU usually 27-31C and motherboard ~25C in a 22C room. Now the Duron is a different kettle of fish :)

If I had the option I would substitute 120's for the 80's and put them together on a single rheostat. I'd bet running them 1/2-speed would cool just fine and be quieter.

For 75 bucks you could slap together a decent watercooled rig which would be very quiet...

My setup is 120 (135CFM) intake, 50 (21CFM) exhaust, 80 (20CFM) exhaust, and a 120 (90CFM) exhaust...sounds like a bloody hoover, though the case is one degree over ambient
