Arrived on time and clean as a whistle, inside and out. I was pleased to see it arrive with Win10  Pro ready to activate, a very usable Logitech USB keyboard, usable generic USB mouse, and working HP DVD Read, Write drive.After activating Windows and getting the updates current, I cloned the drive to a new WD 2.5" 1TB SSD, keeping the original is a backup. I also dropped in a WD 3.5" 7200 rpm 1TB HD for storage, a Gigabyte GE Force GT1030 low profile video card with its own ram, a TP-Link PCIe Wi-Fi card and another 16 gigs of matching DDR4 1700 CL 15 1.2 volt ram (love having a spare parts bin to raid), a Bluetooth dongle and called it done.I ended up with a nice machine for the home office, photo editing, light gaming, video work and general web mucking about for the price of the computer and about $80 for the SSD. It boots in about 16 seconds, has 2 TB of storage and 24 GB of dual channel ddr4 ram. Overall I am very pleased with the purchase and may pick another to use as a media/plex server, another project.The HP maintenance and service manual says the TPM is "field upgradable" from 1.2 to TPM 2.0, but that is a project for another day.I was able do the "Field Upgrade" to TPM 2.0, and do "by pass CPU check" hack (found online) and get it run WIN 11 with no issues (7 months now) not for the faint of heart though.
