This is right above your price range, and I would look for 2 sticks of RAM, but overall this is a good build that will give you some decient performance. You might be able to find all of this on ebay at the right price.
@above, hes from UK. tigerdirect i dont think ships to UK
Once again, its a refrence... he was also going to buy the stuff on EBay...
Ask for more money. Other than that, try to get a phenom if you can find a cheap one. Minecraft really hurts the CPU.
I would go with a APU honestly, Phenoms would be a little overkill for minecraft... Any of the A6's could handle it, and I think a A4 could as well.
Thanks for suggestions guys, i will try get him to bump up the budget for me lol
