You might want to consider an Athlon (maybe underclock it) - the AMD IXP 
700/800 south bridge seems to work well with FreeBSD (in my 

These boards (eg Gigabyte GA-MA785GM-US2H) have 6 SATA ports (one may be 
eSATA though) and PATA, they seem ideal really.. You can use PATA with 
CF to boot and connect 5 disks plus a DVD drive.

The CPU is not fanless however, but the other stuff is, on the plus side 
you won't have to worry about CPU power :)

Also, the onboard video works well with radeonhd and is quite fast.

One other downside is the onboard network isn't great (Realtek) but I
