A:Answer Depending on what type of harddrive you bought, there are 3 types on this pc. M.2 slot nvme pcie, sata 2.5 ssd or 3.5 inch hdd. m2 slot is usually above (graphic card) pcie slot, there is a empty 2.5 ssd bracket above the psu shroud and 3.5 hard drive bracket at the bottom near power supply. You would also need to purchase a sata data cable if you are adding a 2.5/3.5 inch drive, sata cable from hdd to motherboard sata port and need a sata power cable from psu to hdd. After installing, if it's a new hdd you will need to format it in windows. But google installing hdd and there are ton of videos to help with install.
