i'm going to buy a new case and i want to put enough fans to keep my system cool.

looking at the front (with the floppies facing you), are the fans on the left side blowing into the case? what about the top? i know the fan on the front should be the intake and the one on the back, besides ps fan, should be the exhaust. any suggestions?

right now i have a 300w ps and i'm running 3 fans (2 case 1 processor). what is the max # of fans you would recommend i run with this ps?

900mhz thunderbird
640mb ram
nvidia gefore 256 32mb
56k modem
hp cdrw
3.5 floppy
usb pci card
