It's using two sdram dimms in parallel on the memory bus. It's got one
33/32 PCI bus, one 33/64, and one 66/64 bus. I really can't find any
bottleneck apart from the disks seeking like idiots.

Are the disks syncing the array ?

cat /proc/mdstat with software raid.

That might explain the disk activity. Hardware raid may be a bit different, some don't need to sync and others scrub the whole disk.

Cheers
