Acer Aspire desktop PC in good condition

Bought this in 2016, and has served me well for many years. No operating system included, you will need to install Windows, Linux, etc. yourself. I have upgraded several parts (SSD, power supply) over the years, but the HDD in there is original (8 years old), so you may want to replace it.

Full specs: Acer Aspire TC-710 motherboard Intel Core i5-6400; 2.70 GHz, 4 cores, with integrated graphics 16 GB RAM, DDR3 1 TB Western Digital Blue M.2 SSD 3 TB Western Digital HDD Thermaltake 500W power supply CD/DVD drive Wifi, Bluetooth

Note: I also have a 120 GB Samsung 850 EVO M.2 SSD if interested (see last photo); I can throw it in for an extra $20.
