This HP Compaq Elite 8300 is an excellent computer. For the money it is functioning better than I anticipated. After getting it up and running, I have had no issues at all. Compared to my older HP desktop which is a DC5750, this one is lightning fast. Primary drive is SSD, secondary (storage drive) is an HDD. I cannot complain at all about this machine. A little touch up paint on the outside makes it look as close to new as possible. I am seriously impressed with the functionality of this computer. Some write on here a few gripes. I cannot see what they are complaining about. This machine arrived clean and ready to go. And YES you can add more RAM if you want. It's up to you and your money.
