Got an idea for a M1000 Epia system in a maplin project box, but replace the heatsink/fan with a big copper block. This block then touches the case surround for a huge surrounding heatsink. Add to that a 55w fanless PSU and a single 120gig harddisk - also with a copper block, but also packed in foam.
Truely silent system? Cooling good enough? Considering its not painted and plain alu. 55W is enough for just 1 harddisk, no CD drive and the M1000? Perhaps a couple of LEDs too
