The unit arrived in decent shape (there was a sticker residue on the front).I booted , registered without issue. OMG was this fast compared to my old Dell 780 .I had been using for about a week, when I thought to check on drive space .  118G WOT!I popped the cover, sure enough there was a 3T HD ??Brought up the BIOS screen. THE SATA PORT2 WAS NOT ENABLED.Did that and the drive showed in the Disk Manager... BUT it was not formatted as a discoverable drive.In addition, it seems the user needs to be able to assign usage (that assumes we know / and I guessed ) .Please have the system Ready for typical Users. The ones that need differences will probably have an IT department doing the setup.
