Just for the record here is the bonnie++ output (version 1.02) on our
fileserver. It is a Duron 950 machine with 256MB DDRAM memory, an elitegroup
mainboard with SIS Chipset, a 430W Leadtek power supply, two extra fans for
the HDs. The array is RAID5, six IBM DTLA 3070545 on four Promise controller
cards (only masters, no slaves), two of them PDC20262, two PDC20268. A
maxtor Maxtor 5T060H6 hot spare (currently not yet assembled into the raid)
is sitting on the fourth controller. The filesystem is reiserfs with quota
enabled. The kernel is 2.4.18-pre3-ac2 with reiserfs quota patches.

The performance is not stunning but it's main purpose is serving files via
samba on a 100MBit/s network which it does rather well. It took some kernel
revisions to run stable (I started with 2.4.0pre9, the first stable running
version was 2.4.6, the performance increased some revisions later)
I spent some time installing the thing and keeping it running. Once one of
the controllers went flaky, resulting in strange hangs in the booting
process, once the mainboard went dead. But the good news is that it is made
of stock (and rather cheap) items that I can get in every store around the
corner and it had been no problem reordering the disks or exchanging
controllers. The root fs is on ext2 though, for simplicity. I would strongly
recommend that. It's contents are rather static and easily restored from CD.
