I can see you ' ve already looked at Phillips hue , that was what I would recommend for the colormood lighting . Whenever someone tells me they ' re looking at rewiring I always recommend nothing less than cat 6 a since it will handle 10 gbe for the most part as that becomes available on consumer gear . Goes without saying but make sure to have good 5 ghz coverage and 5 ghz compatible systems . Most ha stuff operates on wifi , don ' t want to be cockblocked by the lack of channels on 2 . 4 . As far as storage goes , this really depends on how far you want to be able to scale out . Until you mentioned the 4 k camera I was going to recommend a simple 4 bay nas , but it looks like you might want to invest in a small soundreducing rack you can shove in the garage or under some stairs , and that can hold your routingswitching as well as storage and selfhosted apps . One thing I have been looking to implement myself is a reverse proxy with squid that will cache traffic to some ssds . Facebook and Netflix loading at 10 ms will be very nice .
