i got addicted to gaming and so preferred sold it and work.
about guide i mean step by step guide to mod a bigger case into a tiny pc for example. i just only very recently got knowledge of a big market already existing on that. (mini itx, etc..). i'm new to pc world.
Yeah i was kind of also looking into this, but i really don't know sh** about that. seems that an usb stick is required, and that somehow i would transfert from my laptop to an usb stick that i will after plug into the nvidia shield that will finally stream the 4k content. seems weird to me. i don't know if i can stream from a non 4K capable laptop on the go on the shield that will decode it and playback. i just checked and compared hdmi 2.0 bandwith and wifi bandwith.. yes that's kind of not possible. But if the shield could work as if the laptop was a streaming source like netflix, maybe it could start the movie before the end of the full movie data received. but that would be tricky, as 4K content often use 40gb space, meaning that the shield would basically need to anyway save the movie on the usb stick plugged in it.
anyway yes i'm slowly considering there is no such things as cheap alternative if i want to stay small. unfortunately small mean no gpu, so expensive board because h.265 only supported by also recent cpu. because a cheap old second hand itx board could have been a solution (with an old cheap gpu that just do 4k playback and a crappy cpu).
maybe I should also simply considering a nas that do h.265 decoding. i already have a cheap nas (the first price synology), so that again would be not nice to buy a second one.. but anyway.. looking into solutions..
for me the real problem is my macbook. it's an early 2015 macbook pro retina 13", cost like 1400$ new and i can't even add an external gpu on it (only work on 2016 models), would have been a windows laptop i think i would have found a solution. grrrr
