Am I the only one that prefers the PSU in a brick rather than in the console? I'd prefer to keep as much heat away from the console as possible, and cut down on as much noise as possible.
I assume if they put it in the box it would be:
a) bigger
b) hotter
c) louder
It is annoying to have to find space for it, but that inconvenience is worth it IMO.
Maybe a hardware refresh in a few years will give us a slim version with:
* No optical drive
* 500GB or 1 TB SSD
* Internal PSU, with quiet cooling and not a tremendous amount of heat
Edit: Yeah also what Woo-Fu said re: being able to produce same hardware for different regions and just swap out the brick instead of the whole PSU - easier manufacturing. Plus as others have mentioned if an internal PSU goes bad that's a bigger deal than buying a new power brick.
Does anyone think PS4 will have an internal PSU? I would be very surprised with that much power under the hood. The thing would be a beast of a box.
