Nitroxx, can this upgrade be done to a Sony PS3 40 GB version as well? What is the actual difference between the 40, 60 and 80 GB versions of PS3 other than the drive size? I feel if there is no difference other than drive sizes then a 40GB PS3 + a 320 GB drive would work out much cheaper to run. Let me know so that I can make my purchase accordingly.
