I agree with what everyone is saying. A 40" TV is ridiculous. Whether youre using it as a TV or Monitor its just dumb. As a monitor, youll been looking around a lot and having to move your head around like that will pain your neck. You could easily just have a 24" Monitor and be great.
As for the Macbook, where do I start. Its ridiculously overpriced unless you get a second hand one. (Which you should definitely do)
As for the "gaming PC" considering you put gaming in there, you already know that its not necessary.
Alarm clock? Its 2017 just use your phone.
