Hi
Fanless Atom motherboard / solid state disk / wall wart power supply ... DVD is still the main source of noise. Of course the bean grinder in the single cup Cappuccino machine drowns out the DVD pretty effectively. -------------------- Looks like a 5370B with an intact front panel and some sort of internal issue(s) just showed up at auction. Hmmm.....

Modern quiet computer chassis is very very quiet while using a multitude of very simple and straightforward tricks like this. Recently built a server with 8 hard-disks this way. The DVD-player is the noisiest part... by far. However, we will never really use it after initial booting, so it is OK. * rubber suspension of fans * rubber suspension of hard-disks * damping on flat surfaces We got a pair of extra large (and quiet) fans to ensure air-flow. Slightly more expensive than the standard chassis. Quieter when in the terminal room than the computer-hall with closed door.
