By ``ECC'', don't you mean ECC capable SDRAM. ;) Looking at my favorite
maker of high quality SDRAM DIMMs, they have CAS 2 capapable (~8ns) non-ECC
SDRAM for 139 USD, and ECC SDRAM for 149 USD. Not a huge price
difference there. ;)

Hmmm... the G3 has: three 64-bit and 2 32-bit PCI slots (one of them
overclocked to 66 MHz for the ATI Rage).

Decent G3 configurations come w/ an Adaptec 2940UUW card. It's a
nice setup
Phillip> G3 uses cheap SDRAM. Power260 uses ECC.
For a workstation, I don't think this is an issue, but this is just my
opinion. I decked out my PII w/ SDRAM w/ ECC, and if I had to do it again,
I probably wouldn't have bothered.

Hmm, I didn't realize we were discussing ``servers''. As just a workstation,
that I picked up w/ 9 GB of SCSI-2 U^2 Wide SCSI, and 256 MB of RAM, for
3k USD,... it's a pretty good deal.
