  1. How can I get the SATA Driver for this? I want to install Windows 7 on the OptiPlex GX620. Thanks in advance.

    1. I have Windows 10 32-bit installed on mine and everything works and runs very well. I haven’t tried 64-bit but the system is limited to 4GB of RAM so there’s no reason to (and it would run slower anyway).
