Used for schoolwork (math programming and processing) as well as gaming. Used 5 Old repurposed hard drives (3T of memory total) and 2 old monitors. Pain to install all the drivers but works fast and well now. Used an old Win7 serial number for the operating system. Added 2 case fans later due to overheating problem with the CPU. Once added, works even faster! For my first build, it went very well!
