Received this PC 2 days ago. It works as promised. Comes with a new Windows 10 ready to be set up (I'm hoping that the key will work if I need to format the HD). Performance is great for the money you're spending. I'll add a HD and graphic card to boost performance. It fits all my needs for a PC, no need for anything expensive. I'm using an LG 21.5" monitor. Recommend buying, if this is what you're looking for. To facilitate, I'm including some specifics of the one I have: CPU: Name  Intel Core i5 3570 Codename  Ivy Bridge Specification  Intel(R) Core(TM) i5-3570 CPU @ 3.40GHz Package (platform ID) Socket 1155 LGA (0x1) CPUID  6.A.9 Mainboard Model  HP 3397 (0x000000D6 - 0x00002258) RAM (2x): SMBus address  0x50 Memory type  DDR3 Module format  UDIMM Module Manufacturer(ID) SK Hynix (AD00000000000000000000) Size  4096 MBytes Max bandwidth  PC3-12800 (800 MHz) Part number  HMT451U6AFR8C-PB Serial number  35874683
