Umm you would need a new power supply... a 220w isnt going to power anything good. Also whats you budget and what form factor is your case?
Budget for now would be between 150€ - 200€
I got that pretty small Case of AX 3960 (Small Form Factor PC)
Random video about the case: http://www.youtube.com/watch?v=EktqMHD_vDQ
