I can upgrade with $900. What do I get? Posting Specs.

I just bought this computer brand new for $100 and I have $900 to spend on it. I need it to be wireless, other than that i'm just going to be using it for business. I'm looking for best performance.

The case looks to be very small?

I would say that NOTHING can be upgraded . Even if yu could add a more powerful processor [ which would be at least two generations old now ] its unlikely to cool that well in that case .

Buy a USB wifi stick to connect to your network
and spend the other $880 buying your mom a present
