Re: Upgrade Old Amd K62-500 Packard Bell
I live in the US so I can't direct you to anything, but I would suggest just getting a whole new system. Cases arn't that expensive, most come with new power supplies, and you'd be getting most everything else.
As for compatability, you shouldn't have too much of a problem. Many boards still come with drives for most OS's, and on your budget, you'll probably get something older anyway. Also, if you find a good deal, check out their website and see what support they still have for the board...
