The only thing that scare me about 'real' servers designed for corporate
use is the non-standard parts, like drive sleds, RAM, etc.
Back in the day (here I go .. rant mode) you could buy reasonable
quality hardware without going to a full blown server. Usually that
meant going SCSI instead of IDE, or buying Matrox instead of Diamond.
Those days are over.
I also know nothing about PC server class hardware, which is going to be
a problem. It's hard to see the gotchas.
