The Top rated seller is correct.
You did not fill out the My Computer specs in your User CP for this site, and I don't see that you have told us if this is a Laptop or a Desktop?
As the seller said, if this is a desktop, you will need an adapter 3.5" to 2.5" caddy to install the SATA 2.5" SATA drive into.
Before installing, check the Hard Drive Mode in the Bios, it should be set to AHCI, but check as it may be CSM/Legacy and you would have to change it to AHCI.
But WHY!! would you buy a HDD with Windows on it, when you can install Windows 10 yourself on a brand new, never used HDD/SSD???
