Additional Comments: My mom needs a computer for her work. She is a high school teacher so all it should be is simple power points, word documents, web, etc. My dad should be able to get windows cheap through his work so we are just going to leave that out of the current budget. Now here is the catch. My little brothers have been bugging me to let them use my current computer to play games on. Fortunately these games are easy to run, such as minecraft. They also have a ps3 to cover any of the more demanding games. So would an amd apu be the best option or would a cheap pentium suffice until a potential graphics card upgrade. I would also like the motherboard to have a hdmi port. Then there is the hard drive. Our family laptop died a while ago (reason for this build) and the hard drive is still good. I already backed up the data so could I wipe the data and reuse it for this build? Thanks in advance for any help.
If you live near Microcenter, they have pretty much everything for cheap. You can get an AMD Phenom II x4 for $100, and it comes with a free mobo. You can get a good mATX case for $20 from there. The PSU included with that case up there is very cheap, and it's better to get a separate one.
If you don't have a Microcenter, just get an APU from AMD.
