2019 Dell OptiPlex 3060.
Great little machine, had been using it in the living room as an emulator for retro games since it's roughly the size of an original Xbox One.
I've already upgraded it from 8GB Single-Channel to 16GB DDR4 Dual-Channel, and swapped the 500GB spinning HDD to a 500GB WD Blue NVMe SSD for quicker boot and read/write times.
Legal Windows 11 Pro installed and activated, and it's been reset with a local account so you can sign in with your own MS account if you choose.
Unit has been disassembled, the board and interior was cleaned of dust, the exterior panels have been washed and disinfected, and the CMOS battery has been replaced.
PC tower, power, and HDMI cable included.
$140, cash only.
