am I better off going with a CM MasterBox K500 + MWE 650 Gold bundle ($84.99 for case, $99 for PSU seperately and $140 in a bundle) or Cougar MX330 + Enermax Platimax D.F 600w ($45+$82)? According to some reviews the enermax is a little better than the MWE, but I don't know how the cougar case holds up against the K500. I mean, there has to be a reason it costs almost twice as much right?
