Nothing comes with a BR drive so this is a DIY project, which means an Intel CPU base and currently there is no recommendation on the GPU to partner with. Intel continues to fluff the specs of its boxes; there is always something wrong/missing from the spec. nVidia is heading towards the landfill due to their continued insistence of following different standards to all the other vendors (we may have a fun choice to ditch support for them in the future). AMD appears to be in league with Intel. Even in the ARM space there are challenges; we are in the middle of rewriting Kodi-on-Linux graphics around V4L2 and currently none of the existing main players (Amlogic, Rockchip, etc.) have mainline kernels and the proper software support .. everything is still "work in progress" and it's too early to tell how things really play out.
So, as what you seek is a unicorn that doesn't exist, pick up a cheap SBC device that will tide you over for a year or so until the real-world catches up with the dream-world.
