I also like it that Sony was cool with them doing this.
Despite Sony's insistence on DRM they make some very repairable hardware. For instance, it is dead easy to replace the controller switches, battery, and other parts on the Playstation Vita where the flex cables are very well routed.
The PlayStation Portable was equally he say to work on, replacing any component was super easy. And to a very large degree repairing the PlayStation 4 is also pretty easy, of course most components are soldered on the motherboard but if you only needed to replace the fan or the the power supply that's very easy to do.
