Here you go Peter, this reference is a complete explanation of all OptePlex
computers, by date:

My suggestion would be to stick with Dell. I've used them for what feels like
forever (including at work (Boeing)). I'd also recommend that you look at the
Dell offers during (or just before) Black Friday. They always have pretty good
deals at that time.

My faithful, almost 10 year-old Dell Optiplex 980 is doing two odd
things. I do plan to replace it after Christmas, when (if?)
unload-the-inventory sales kick in. But in the meantime:
1. Whenever the power goes out, I have to crawl under my desk, pull the CMOS
battery, and put it back. I can't just hit F2 and fix the configuration because
the internal error checks kick in before "Press F2 for setup" happens. They
display lights on the PC front that Dell does not document meaningfully. Once
CMOS is reset, I find that the date and time are forgotten, and more important,
the disk configuration forgets that it is a non-RAID AHCI SSD disk. Once I set
those two things straight, all's well. No, it's not the battery, which reads
slightly over 3v on my multimeter. And I've replaced the battery twice, with
the same results. Everything else in the BIOS is as I set it previously.
