Minecraft PC Build for brother before I leave to college in a month

[Hazarded]

Hello I usually let my brother play on my laptop because his chromebook well doesn't play games. I was thinking If I could rebuild an old working computer that is reliable into a new minecraft gaming one. That pc has been around 7 years and is running an intel pentium. I do not want to any parts besides the case and optical drive because at any moment those parts will give out.

Needed:
Windows 7 OS, he's too young to understand windows 8
Under $400 could stretch it to $500 but that would come out of rent and book money

DO not need optical drive or PC case

Any input would be welcome since I will be going back to college in less than a month so I will be wanting to build this before I leave.

Thanks for all your help.

Made this. I'm not even sure what minecrafts system requirements are but i'm sure this is overkill and can get away with intergrated graphics. I'll try to remake one with intergrated graphics that can run it but I made this for now as a possibilty although it pushes your budget

Minecraft relies a lot more on CPU than GPU, a quick processor with integrated graphics should do fine

Heres one with an APU which has decent integrated graphics. Runs Left for Dead 2 on Ultra ~30fps from the benchmarks I saw and im sure L4D is much more demanding than Minecraft. This build keeps the budget this time

You should change the ram from a single stick to at least dual

Theres no need. Minecraft needs 2gb of RAM and the guy said his brother is too young to understand Win8 so any performance loss from single-dual channel will not be noticed.

So any of these builds would run minecraft at medium settings right?
