Nope. Very quiet. One of the neat things about the cooling technology is that
the cpu heat is conducted to a radiator & vented outside the case, instead of
the normal ATX setup where you need a fan to distribute cpu heat around the
case, then at least one other fan to vent the hot air from the case.

The cpu/case fan only gets noisy when things really warm up, otherwise it runs
at a pretty quiet reduced speed.

The shuttle has 2 fans, one small one for the power supply, & a combined
case/cpu fan. My guess is that ambient temp inside the case is 10-15C cooler
than similar configurations in standard cases. Which is both very good for the
components and good engineering. It also makes for better cpu cooling, as in
this system, air is drawm in and vented once, instead of an internal cpu fan
which re-uses incoming air several times (on average) through the cpu heat
exchanger before venting it, thus using pre-warmed air to cool the cpu instead
of fresh external air.

The things that have impressed me most with this system are the cooling & power
supply engineering. To run a system with XP2600 cpu, 1Gb DDR333 memory, dual
GeForce4 graphics & 7200RPM HDD on a 200w rated power supply is unusual, & to
squeeze everything into a box the size of this one & run cooler than a normal
ATX system is impressive. They look good too :-) 

I have been told that there is a fair sized cluster based on Shuttle SFF boxes,
lots of bright blue power LED's. Not sure where this is though.

Cheers
