Nice elegant design :) I just wonder, was the simplicity in style of the 50's and early 60's in USA inspired by the post war austerity designs (like the Utility designs of the immediate post-war period here in the UK and Europe) ? The designs always look cheap to build (like most Ikea stuff today ;)...

Not sure what to do next Does it get warm/hot with no load? I'm thinking your power meter may be reading/displaying fast peaks rather than a true power reading. If it is drawing 20watts from the mains it will be generating 20watts of heat so will get significantly warm. If it runs cool to touch it ...

OK I received the heatsink today an I already installed and tested the bad news is that even with 25Watt it will not be able to run passive.
That heat-sink is designed to have forced airflow (i.e. in close proximity to a fan). The close fins cause too much drag for efficient convection cooling.

My other question is: do you think this setup will be sufficiently cooled completely passive? I'm sure it's possible, but you'll have to design the whole system with some care for it to work well. What CPU heat-sink do you propose to use? I have not seen any thermal resistance figures for PC type c...

having the air snake round a channel on the outside of the case before entering the main body then have a fan suck the air out through the heatsink and through more gentle twists round foam. The second idea would be much more fun to build, so I'm leaning that way. I suppose the question here is: Is...

Regarding the foamed rubber, are you saying that I should put this in the enclosure for the drive to rest on?
Yes. The gel pack will not support the drive it'll slow squash as the gel move in the bag. You need to support the weight of the drive with something compliant but un-squashable.

What happens to drive temps when the PC is turned off? It falls ;) There is considerable thermal mass in the gelpack so the HDD stays warm for a while. The reduced rate of temperature change is actual very good for the drive it reduces the thermal stress. You may find that, if the overall surface a...

do gelpacks work for 24/7 systems or just ones that are only on in the day? (slow to warm up but need to cool each night or become ineffective) The gel pack works in two ways: It kills sound by absorbtion and the viscous gel is heavy, so adds mass, so damping higher frequencies considerably. It con...

Why not? Pressure possibley - there's usually a low pressure in a heat pipe, it would require thick-ish copper (i.e. more expensive/less profit) to prevent a single pipe distorting across a flat surface.
