Is this the one you are referring to ($34):
http://www.amazon.com/TICTID-Android-Amlogic-Lollipop-Streaming/dp/B0196GIUUK
Quad core Cortex A53, 1GB RAM, 8GB NAND, 4K@60fps H.265 hardware decoding, etc.
Another one @ $35 with an HDMI 2.0 port:

Very nice specs for the money.
Be very very careful with dropshipped Android boxes:
-> Most have no support at all. You'd be lucky to get a single OTA update
-> 4K doesn't always work. Depends on the rip (see cnx-software).
-> Amcodec in Kodi is still twitchy and all over the place. Stock video app is better
-> Avoid Rockchip or Allwinner SoC, Rockchip has poor support in the first place
-> The kernel build is an old 3.x release which dies this year security wise despite running Lollipop
-> No support for Netflix HD due to lack of DRM support
-> Possibly no auto 23.976 switching
-> Some have poor build quality and overheat
I have one coming in to replace my old WDTV but do note their limitations. Why do you think they are all $50 or less? If you are looking at one that is $100 you are getting ripped off. For offline 1080p and below playback sure. For a perfect all rounder, buy a Shield (if you are not in the US, the Shield is half useless).
OP, your build has no HEVC support and will dump a lot of heat power. Otherwise it will do fine.
