Definitely wait as Jussi said, but @Chunhao_Lee 's system will do what you need - and then some
The last update I saw was he is outputting 12 channels of DSD256 (Merging Hapi Mk2 and Merging Anubis from memory) for Dolby Atmos content… But can’t recall his PC details.
If you wanted a system with headroom for 5.1 channels, copying his PC would do it
