Purchased from STG Global (renewed units are lumped together so reviews are seller specific). Packaging was better than expected.  Included was cheap mouse, cheap keyboard, tiny usb 2.0 802.11n wifi dongle and a brand new Dell 65w adapter.Not going to complain about the mouse or keyboard, never planned to use them.Easy to replace the sata SSD, m.2 NVME SSD and two DDR4 RAM.  Only one knob screw to remove the cover by hand. One disappointment is there is no screw mount to hold the end of the NVME SSD. It ends right where the mainboard is affixed to the case with a screw. There is an extra M.2 connection for wifi/BT module (no built-in antennae).  USB 3 ports transfer speed meets specs.The unit is great for office work, browsing, watching media. It can even run PS2 emulator at 30-50 fps on most games with default settings but it gets hot quick. If you're going to do light gaming in a warm area, be sure to use a desktop fan to force air circulation. I'm in Philippines where we mostly use fans not air conditioning, ambient temps about 80f.Was going to install Linux,  but it works so well with a debloated Windows 10. Why fix it if it aint broke?
