I hope you didn't really mean "18,900 dollars".

Current prices are:

dual 2.8xeon + chassis + 2gb RAM, plus 2 x 36 gig U320 15K scsi drives, plus the
usual HD power supply, etc, for under $4,000.  You mentioned 146 gig scsi
drives.
I bought three of those for my new ftp machine (there are no 15K 146 gig SCSI
drives that I am aware of so you take a rotational latency performance hit by
backing
off to 10K) and paid just under $1,000 each at MicroWarehouse.

If you meant 8,900, that is closer to reality, although it seems high to me
looking at
dell prices.

I can't answer the speed issue with respect to fritz.  Crafty on my dual 2.8
runs at about
2.5M nodes per second.  This is with the quad-pumped 100mhz (400mhz claimed)
FSB.
Newer xeons are quad-pumped 133mhz (533mhz claimed) and should be even faster.
I'd
suspect Crafty might get close to 3M on that machine, in a position where it
gets 2.5M on
mine.  I have no idea whether fritz is faster or slower in raw NPS however...
