SSD's have a very finite life. I can't go into details on what makes/models
have longer lives, or ways that different companies extend SSD life, but any
enterprise application using SSD's for performance reasons almost considers
the SSD a consumable of the system. Even consumer products
I have to admit I like Dells as well. They seem to be pretty well
designed.
My network server has a fairly old motherboard with an AMD 500MHz
processor. They don't run as hot as modern CPUs so it will run fanless

With SSDs, the situation is principally different and, in the absence
