Buy any higher end AMD APU (CPU + GPU), a feature-rich motherboard, and a nice looking case.
Head over to newegg to check out some options. I don't know if they ship to you, but there's nothing wrong with looking just to get some ideas. Look particularly at mini-ITX and micro-ATX motherboards and try to find a matching case.
The truth is there for those who choose to see it.
