I'd suggest buying the case and PSU seperately because most power supplies that come with cases are...bad.
For proffessional looks, Antec, CoolerMaster, Liam Li and Silverstone all make good cases, and for more of the mod/gamer look, Thermaltake and Alien are both good choices.
Good PSU manufacturers include Ultra, Antec and Thermaltake.
