Pre-Built Gaming Desktop or Laptop under $300?

I want a computer that can handle games like Minecraft and TF2. I can't, I repeat, can't build my own PC, so stop pushing for it. I'm aware that it is cheaper and better, but I want a premade one. I also want the OS to be Windows XP or higher. At least 4 GB of RAM and 320+ hard drive space.

For under $300 ehh, look on ebay you might find a standard desktop that could run minecraft and tf2 on low but you would be pushing it

You're not going to get a good gaming pre-built computer for that price. Windows XP is no longer supported by Microsoft and Windows 7 is about to be no longer supported. The absolute minimum amount of RAM that you should get is 8GB.

Check up on your local cragislist, there's always pre-build gaming rigs out there.
Bought my liquid cooled one for $500, two gtx cards and a $600 processor.

Your best bet is craigslist, or eBay. Wait till Black Friday / cyber Monday and maybe people will sell their old PC or laptops then. Or find yourself a new one.
