A Linux Dual xeon system will outperform your F50 by a factor 10
(estimated guess). Get a decent dual Xeon from Dell, with 2 or 4 GB ram
in it. If you can manage it with 4 or less GB of ram, keep it under that
limit... Linux has support for more, but it's not as optimal. Grab a
3Ware 12 disk card. It's a RAID card, your OS sees it as a scsi device,
but you can attach 12 hot swap IDE disks to it (12 x 160 GB or 12 x 200
GB? Is that enough?) Configure the disks in RAID 5, or even RAID 0+1.

For the price of such a system with IBM or Sun, you could even afford 3
of these!
