Whacking great big heatsink radiator fins on the front and side of the chassis. Now if boards were designed so that hot things were protruding above the rest of the board components (e.g. put the CPU on the other side, by itself), you could flush mount it to the biggest heatsink a CPU ever had. ;-) I think passive heatsinking, when done that way, would be enough. Likewise for bolting the hard drives somewhere directly to the heatsinked chassis. That could even help with noise prevention, being rigidly mounted to a solid lump of something, instead of resonating inside a thin metal cage vibrating inside a thin metal box. It'd make it harder for the smash and grab thieves too, if they had to bring a sack truck with them. ;-) -- Don't send private replies to my address, the mailbox is ignored.
