The computer is real nice, my only compliant is not enough usb ports and would prefer the dvd drive be in a horizontal position then vertical. Speed is good, connects it internet fine.

Came quickly and as ordered. Only problem was the extra memory wasn't fully seated so the computer wouldn't boot at first, but that was easily adjusted and works great.

I have had this computer for 2 weeks. So far, my experience has been good. There has only been one incident so far whereby the computer froze upon start-up. Hopefully, this will not occur again.

Only been up and running one week; replaced a Vista. Seems OK. Some differences needing to get used to. So far, so good.

Replaced a Dell Vista, 2006-2008? maybe. Getting used to different locations and icons. Time consuming, but so far so good.

It wasn't easy to GET it to where I love it, but now === with a little work it screams.

The Dell 3668 has all the features one expects a Desktop PC to have, including several USB ports. The supplied software actually includes a few games, which is unusual for a box with Windows 10 Pro. The response seems quicker than my Dell 660 which is a year or two older.

The pc has everything that I wanted with the exception of two items which are easily upgradeable; 8G of memory upgradeable to 16 and 2.0UBS connectors upgradeable to 3.0 whenever the need arises. PCMover was provided free with the purchase-- the program is excellent.
