Not all. All parts that have electronics in/on them use energy and thus produce heat. PSU's are never 100% efficient in theri energy conversion. I'd say 75% Mac heat, 25% psu heat. The mobo with the CPU and the RAM comes first, is my guess, followed by the psu and the HD. Chips on Nubus cards can also get pretty warm. I'd snoop around in there and try to determine what gets hot and what not. Taking out cards frees you from their heat and theoretically also form a bit of psu heat, but that will only be marginal. Also, with electronics: mostly, they don't die instantly form overheating. But the warmer they get, the shorter they live. -mart -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
