I am putting a PC together for my sister and it is a very basic setup. It's an old Dell Optiplex GX150 with a P3 and Win2K on it. She'll only be checking mail and burning cd's at the most. This is why I don't want to put a lot of money in a CD burner. I looked at NewEgg and found some I liked. Is it safe buying an OEM and will it come with the installation disc? Any reccomendations would be appriciated!
