I’d like to buy an instant replay box using Vmix. I don’t want to build a custom pc. Are there any pre-manufactured machines I can order that would fit the bill. I do not plan to use a capture card, but instead have all my inputs and outputs through NDI. I would however like the option to add one or two capture cards in the future if needed. I highly doubt I will. I am assuming a $3000 budget seems about right for the hardware. I don’t mind spending more for a machine that performs flawlessly. The box will strictly be used for instant replay only in live productions. We will not be installing any other software besides Vmix on this machine.

That would be awesome but don't I need more resources in that tiny box? How important is the GPU? I'd also like to record internally.

i have this board, https://www.asrock.com/m...ac/index.us.asp#Overview it is very small and has thunderbolt 3, so expand all you want later on. i have a I7 8700k and 32gig of ram and intel optane with a 6tb wd black. works great, and it will cost you way less than any turnkey solution.
