Well, got this tower model as it has a full height PCIe slot.Haven’t powered it up yet, as it only has a VGA out and I don’t have a cable (isn’t everything HDMI now?).Anyway, it’s clearly once used and returned as there was a missing card cover at the PCIE slot on the back and I think I know why - card fits but the power supply doesn’t have a six pin cable to power it.I pulled a better power supply from an abandoned computer to fix that but discovered it’s 1/2 inch longer and won’t get past some of the Dell frame hardware.So...will report back when I either find a solution or return it.----Update: gat a 400w power supply with the correct form factor and a 6-pin power lead ($35), installed the PCIe graphics card and everything seems to be running fine.  If it crashes I'll post again, but otherwise still a great value for less than $300.
