[Soekris] cooling fans for net4801

[snowcrash+soekris]

hi,

back in 4/2005 @,

  http://lists.soekris.com/pipermail/soekris-tech/2005-April/008145.html

i read,

"Next version of the net4801 case will have better ventilation, next
version of the net4801 board will have a dedicated fan connector, and I
will work on selecting one of those small 20mm or 25mm fans to fit...."

looking at the current 4801-60 spec,

  http://soekris.com/net4801.htm

i see no mention of a fan connector.

IS there one?

what fan config (cize, number, power supply,etc), if any, are folks
here recommending for the 'right' cooling/noise balance?  in
particular, for an HDD config ...

thanks.
