Totally clean inside an outside. Really excellent rating means it looks like new. Dell Optiplex 9020 MT is a full size tower. Upgrading this tower in the future will be a breeze because there is plenty of room to make changes add boards. The 4 core is still usable , when the 6 or 8 core becomes cheaper its going in the tower.  Other refurbishers can send something else like a small form factor. When a full size business tower model was shown, substitution is something I don't like.
