WINDOWS PC I bought it and didn't use it due to lack of time. I changed the graphics card to a 5060 and it comes with a 3050 card. One terabyte of memory. I don't know the rest of the details because I didn't figure it out. It comes with a monitor I bought from Extra on sale for 999 for gaming, and a headset with it, and all the PC accessories. Just plug and play. Operating System: Windows Graphics Card: Dedicated Processor Type: Intel Core i5 RAM Size: 16 GB
