The biggest expense though was the >memory. around 4 thousand if i remember right OK. I haven't tried to run a configuration like that thru dell recently. I generally try to buy a complete system from them, less the hard drives which I can generally find elsewhere at a significantly lower price. Since they are hot-swappable, it takes four screws to mount the drive on the "drive sled" and you slide it in and run, no jumpers or anything as the backplane has that hard-coded for each slot. 10K 146 gig drives are just under $1,000 at MicroWarehouse, as I said. I also bought my 36gig Seagate 15K drives (U320 scsi 80 pin) there as well for about $600 bucks each. DDR RAM isn't terribly expensive, but I haven't priced it for a 533mhz FSB since I don't have one of those here to deal with. For my 400mhz FSB box, 1 gig was not that expensive although I don't have the quote in front of me to produce an exact price. But I don't generally buy third-party memory, it can be _way_ problematic.
