I am looking to build a desktop computer for under $300. I would like to be able to use a hdmi connection so I can use my tv as my screen. I only used my laptop to download music and check email.I don't play video games. I bought the windows 7 update and i have an old Dell xp recovery cd which I am not sure if I can use that to install on a blank hard drive. I checked out barebone nettop are they any good?
