Hey guys. I currently run sql server locally at work on a desktop. I was thinking that I may upgrade the system, and was looking at the cost of getting an actual server vs a desktop from Dells website. Basically I can't figure out why the cost is higher for a server than a desktop with similar specs. Now I am talking about a basic tower server. Not rack mounts, or blade servers. I know that some tower servers are designed with redundant power supplies and such, but I am look at ones without it. So is an Opteron any different than a Phenom X4 of the same clock? Or 8GB of UDIMM (this is what Dell has for their servers) versus regular desktop DDR2 or DDR3? Or the hard drive they traditionally put in these boxes? (Both were 7200 rpm). Similar specs came out to be 200-300 dollars more for the server. Thanks.
