Projetc live boradcast

Hello.
I am putting together a project from a pc for live broadcast.
I need to use 5 blackmagic decklink mini recorder 4k and a blackmagic decklink mini 4k monitor.
I need to know if this is possible, and if so, which motherboard configuration to use?
Thank you.

Never tried myself, but the forum is littered with posts / questions similar to this and almost all say 2 mini recorders seem to be the limitation, any more usually don't get 'seen' by the pc.

If ur purposefully building a pc use an internal PCIe slot card or multiples of PCIe cards to acheivement the inputs / outputs you want.
