Without a very very close inspection, it is difficult to tell that the unit is actually used and refurbished. This third generation i7 Intel CPU is plenty powerful enough for the majority of users. I removed the case cover to inspect the inside before I even powered it up, and it extremely clean. I installed a second SDHD drive (required mounting hardware) and I use that drive as the backup for the Win10 Pro OS together with my stuff. It comes securely boxed in a box with a easy to ready setup instruction sheet with pictures. I did by the Square Trade optional warranty.
