here are some (kinda blurry)pics....
medical gel pack (purchased at drug store for $1.99 canadian): notice in the top left corner is where i made a tiny opening to drain out some of the gel. it has been sealed with crazy glue, then tape, then more crazy glue, then put in a ziplock bag.
here is the enclosure (hammond 1590 DFL, recommended by forum member justblair, purchased from mouser for $20 canadian) with a gel pack in it and a bit of foam, no cables right now but we all know what those look like. also i have filed out a small notch for the cables to fit through.
added the samsung HD.
added another gelpack on top (the masking tape is holding the excess ziploc bag nice and tight).
piece of foam for the top (not sure if i am going to go with this for sure, it helps things fit tightly but also inhibits the gel pack to box heat transfer. the top gel pack doesnt touch the box but its pretty close)
with the lid on (those are extra screws taped to the enclosure so i dont lose them)
i haven't put this in my system yet but will reply with some results concerning noise and temperatures. feel free to ask any questions.
