Is it difficult to install a computer hard drive on a desktop such as a Dell or HP. I don’t own a computer and have been looking at refurbished for a BI install. Many of the reasonably priced units I’ve found come with only a small SSD, no hard drive or a smaller drive than necessary for recording. Many also with no operating systems. New hard drives seem a reasonable option but it’s the install that‘s the issue for me. New computers are to expensive. Thanks
