I purchased 2 of these and being in IT I had some issues with the builds.- Both PCs had 2x4GB and 1x8GB sticks of RAM. One PC they were all 2666Mhz sticks and the other had two 2666Mhz and one 2400Mhz. This is being extremely cheap in my opinion.- The M.2 slot has a standard SSD not an NVME... Again this is nickel and diming the customer.- The front face of one of them is scuffed up pretty bad.- The Operating system and system drivers are old. So plan to run updates and download the Dell Support Assistant to update drivers and the Bios.- Last, I have no idea where they got the OS image from but on both my PCs they were corrupt and I had to run Admin CMD >  CHKDSK /R and repair the OS of errors.Truthfully I needed these PCs ASAP or I would have returned them.
