That computer you are looking into... stay away of please. Build your own, take your time and read the manual. You're going to waste money, sure it'll run Minecraft but you should save money on something you can actually customize. HP doesn't let you do anything except turn it on and play. If you plan to overclock and make it faster and better than the price was, get a third party motherboard like MSI - Asus - Gigabyte for example.
But you don't need a $1000 computer, you can run it with a $150 computer like mine.
You can get a simple Core i3 with a good ol' GTS 450. Both parts aren't very expensive and will run Minecraft flawlessly, but you should get about 4GB of ram for Minecraft since it's Java based.
This was a short "idea" of what to get. Don't get prebuilt since they're expensive for junk.
My friend is selling it for $150 to me and I can trust him about it. Can I build something better with that small amount of money? I have no case or other parts onboard.
You have a pretty good friend then, because he could sell it for far more than that.
It's impossible to build your own PC for under $300 likely and that's just a basic system. When you build your own system Windows alone will cost roughly $100.
Minecraft isn't very demanding compared to other video games. While that computer isn't really a gaming PC, it should be quite adequate. Here's what you should do:
1) Install FRAPS so you can monitor the frame rate of Minecraft
2) Update your AMD video drivers ( www.amd.com )
3) Install and run Minecraft
4) DISABLE VSYNC in Minecraft
5) Tweak the resolution and quality to the optimal that gets above 60FPS most/all of the time
6) turn VSYNC ON
7) quit displaying the FPS with FRAPS
VSYNC is a feature that prevents screen tearing. You can Google that.
