That is one reason I stopped using Dell. The other reason had something to do
with our Accounting department and Dell's insistence on using a "Dell Card"
instead of a plain "net 30" account.

With my HP servers, if something goes south, HP will send a tech to fix it in
4 hours. The server gets a 48 hour burn in before I even take delivery. Then I
burn it in again to make sure something didn't come loose in shipment.
Sure servers cost more. If it runs a critical service that can't be down for
even a 5 minute reboot, you just need to spend some money. Sure things have
failed, One server has had every hard drive replaced over a few years, but all
under warranty, and since I have spares, there was no interruption to service.
My T1 lines go down more often then the servers do.

My home firewall runs on an old re-used piece of equipment. If it goes down,
big deal. The kids just can't play World of Warcraft until I fix it.

If the e-mail server at work goes down, I have the guy that signs my paycheck
calling my cellphone at 2 AM to fix it.

Reliability is not cheap. And cheap isn't usually as reliable.
