I have a PS Two slimeline with a flip top lid and see sets with swap magic and includes the flip lid for PS two for sale. If I buy the replacement flip top lid for my PStwo, do I need Magic switchs or anything else or does this flip top lid take care of all that. I want an easy solution without having to try to install the magic switches. Also is it easy to install and will it void my warranty at all. thanks for any help.
