I just installed a fresh copy of Windows 10, ready to go. You can use as is or use for parts.
It was built 7 years ago but will still run a lot of newer games at decent settings and older games at ++ settings.
It has way too many bells and whistles to list all on the internet. Some specs:

Intel I7-5930K 3.5GHz 6 core processor.
64 GB DDR-4 Ram. 32GB 2400mhz and 32GB 2800mhz
