I have this working PC , obviosly no support for XP - I would like to use as basic info searching , storing photos/manuals etc. I'm a disabled former auto tech, had my own shop for 20+ yrs - Is this worth updating to Windows 10 , maybe add ram(2 of the 4 slots are empty), a new PSU, I did install Nvidia GT220 graphics card / I hate to pitch it , I could put it on my work bench and still get my cable router wi-fi , is this worth putting a few hundred $$ into it or should I move on ? Thanks ALL !
