... You need extremely strong nerves, a lot of time, rest and a lot of skill to this "heart surgery" at its NDS Lite perform. Just to the look to change it is not worthwhile. Have the housing purchases because in my NDS Lite hinge was broken. It almost worked out ... but after that he was dead, some ribbon cable I did not get it right in somewhere. Have sent him together with the housing to a professional repair service and get it back in this case - now he does it again. Quality of housing is really great, fit perfectly. There are great guides anywhere on the web (eg. As Youtube) for such an operation, but the chances of success are not sufficiently close to 100% I would say for the occasional hobbyist.
