I bought this compact pc to be used at a pharmacy, so mainly just to run office and pharmacy softwares. Perfect size that can be hidden away behind the monitor or right underneath it so they don't take space.Due to comments I've read about issues with overheating due to too much dust inside and on vents, i decided to open it to clean it if needed.  That wasn't the case. No dust particle anywhere and that's hard to get rid off completely.  Mine looks more like an open box or returned item.  I chose Micro Deal as the seller myself instead of letting Amazon select it for me. Perhaps that's the difference from other sellers selling the same item, the cleanliness of their products.It came with WiFi transmitter, Bluetooth, mouse and keyboard
