I'm selling this PC because I upgraded. Some parts have been removed. It's based on a TSUKUMO ex.computer desktop PC mini-tower multi-monitor model MM5J-A180/T. Please check the official website for details. Graphics card, HDD, SSD, and optical drive are not included. The PC case, CPU, motherboard, memory, CPU fan, and power supply are included. It was working before I replaced it. One memory stick has been added. Please understand that this is a used item before purchasing.
