This is a self-built PC incorporating used parts. After installing the OS, I performed a basic functionality check, but I have not confirmed all functions, ports, or long-term operation, so please consider it as junk. Details are as follows: Case: Micro-ATX (approx. 18.5cm wide, 37cm high, 40cm deep - has scratches and dirt, but I believe it functions without issue.) MB: ASROCK A520M-HDV (Micro-ATX) CPU: AMD RYZEN3 3300X (4 cores, 8 threads, 65W) Cooler: Wraith Prism Memory: 4GB x 2 SSD: 128GB (M.2 SATA) Optical Drive: DVD Multi (Only confirmed recognition by the OS) Graphics: AMD RADEON RX560 2GB (Confirmed via DVI port) Power Supply: ATX power supply 400W (No power cord) OS: Win11PRO (Upgraded after installing Win10 - The OS has been initialized, so please configure it yourself.) Other: Everything in the photos is included. Regarding internal wiring, it's a hobbyist build, so it may be rough in some areas. Some parts were used in an environment with smokers, so please refrain from purchasing if you are concerned.
