Earlier this week, I got desktop (DT) version of the Dell Optiplex 780, which is second from the right in the picture. I already had the mini-tower (MT), small form-factor (SFF) and ultra small form-factor (USFF) 780 computers. My recent acquisition of the DT completes my collection! The Optiplex 780 DT that just came in has a Pentium Dual Core processor. I’ll soon be upgrading it to a Core 2 Duo, probably the E8400.
