I can't see from the inside or outside that this computer has ever been used even one day. It looks brand new. The fans inside look brand new. Everything inside and out looks brand new. It came with one Samsung 16 GB DDR4-3200 RAM stick, so I bought a matching 16 GB stick to add to the empty RAM slot. It came with VGA port, in addition to the 2 DP ports, so removed the VGA port and ordered a $14 DP module to replace it to have 3 monitor support. It came with a Kioxia 256 GB NVME drive so I cloned that and replaced it with a Gen 4, 1 TB NVME drive and moved the Kioxia 256 GB NVME drive to the Gen 2 slot. There are two M.2 NVME slots (1 Gen4 and 1 Gen2) but installing 2 NVME drives requires removing the SSD drive bay. All the USB and other ports feel like they've never been used before. There is no BT/Wi-Fi module inside but there is a slot for one. The antennae leads are there too but are essentially impossible to attach to a Wi-Fi module as I attempted it and utterly failed trying. I do not recommend anyone to attempt it.  There's a 2.5" SSD bay inside as well. Windows 10 Pro booted up instantly and updated itself and I updated the BIOS. Windows was already registered and then I updated to Win 11 Pro for free. I also replaced Microsoft's Radeon Vega 11 driver with AMD's own Radeon Vega 11 driver which is from 2024. The chassis is all metal and built like a tank on the inside and out. This computer's hardware and software all runs flawlessly. Everything installed on it and in it works like new. I have no complaints. All hardware was exactly as listed.
