these are free desktop computers that I resurrect from wherever I can and donate them to people who can't afford to buy one so what ever I have in my extra parts stash is what I use in them. yes I do use a lot of old and perhaps outdated hardware but that is how I do this for free. just my time is all that I have invested in these desktop computers. most of my parts are old and outdated but for the most part are still usable for web surfing and some streaming. thanks. poorguy
