The Antec SLK 1600 + SmartPower 300W PSU , used to be around 2.8K. I guess maybe the price has dropped to 2.5K now?
Another alternative, buy any of the regular cabby's, add a Powersafe to the mix.
And sorry, I dint see the Printer requirement - you could cut here and there, the sound card of course and add your printer to the list.
