Existing Optiplex 990 died; needed to get back up and running by putting existing boot SSD in a working system of same model. This worked great, but we had to change settings to say RAID was not installed, and to enable the internal NIC.They keyboard was in the bottom of the box with no protection, and a corner was broken off.  Don't care; didn't need a new keyboard.A refurbished Optiplex is the way to go if you want to save money and don't mind a little risk. Always have a current backup and a spare drive on hand.This came in less than 24 hours, so that was important.
