Hey everyone I have an old Dell Dimensiom E520 desktop still in good state. I would like to upgrade some of the parts in it. First, I would like to get the max RAM memory I can but I don't know what to get. I want to install a cheap graphic card but I don't know which one and which one is compatible. I want to add a wireless card and still don't know what to get. I want the cheapest things please. Could somebody help me and tell me what to get? Don't forget, this PC is just for home work since I have 3 others for gaming and stuff. I'm just upgrading it so it stays a good PC . Help me please :) Kevin
