If you install a good adblocker extension in the browser (such as UBLOCK ORIGIN), this PC would be acceptable for basic web browsing (only few tabs opened) and streaming videos in low-middle resolution (up to 480p).
VGA you are thinking (AMD HD3650), is slow and too old to support feauters of most modern games, because it is based on outdated DirectX 10.1 libraries.
I confirm that Pentium 4 CPUs (socket 478) are unable to install Windows 8/8.1/10 because lack of support of NX instruction; the only (modern) Microsoft operating system you can install, is Windows 7 32-bit.
