Hi, MaxW. Thanks for sharing that. Very nice!

Looks like a completely noiseless system, with flash disk and passive CPU cooling. One question though : what do you use the system for? With only 448 MB of HDD (at a slow xfer rate) and a 266 MHz CPU my guess is not Windows XP :-)

Welll at the moment its running Smoothwall (firewall) but when I make my micro PC (see homepage too) fanless I'll use that for a firewall and run linux on the flash drive of this one and have a normal hardrive used as storage for a file server and set it so that the normal HDD will power down when not in use :)

I did check out the other projects on your homepage. The home FC setup is very interesting. I'm not so sure of the photo of your injury though. I probably shouldn't have been reading it while eating lunch :-)

Really nice Max. I'm just concerned about the other components needing cooling. Normally some of the other components need some cooling, although not the same amount as the transistors. I'm not sure if it is the capacitors or the inductors.

The inductors get hot but the yellow transformer gets hotter. There are ventilation holes in the top and the bottom so air can flow through it. But yeah, it may overheat but if it dies one day it wont matter because it only cost $5NZD and was fun to make.

I got the heatsink from a scrap metal place for $3NZD but you can get them from electronic places :)

Hey Max are you still here?
I just read this post of yours from a couple of years ago.

How is your home-brew fanless PSU holding up?

I noticed in your pic you have a 448M 2.5" flashdrive card.
What were you using the card for? Not your main storage?
