This machine was recently running on Linux Mint. It was used for video playback and web browsing. I'm selling it as I've bought a new PC. I've confirmed it's working, but it's old, so please consider it as junk. It was originally a server PC. The CPU has been replaced, and a graphics card and Wi-Fi have been added. I have removed the HDD before listing it. I think not many people know this, but it's a so-called "Hana-ge Server" (Nose Hair Server).
