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...
