Question / Help OBS 4k Capture Build (Live Studio)

Hi there,

This is going to be a somewhat interesting use case for a computer designed for OBS. (tl;dr at bottom)

What it is:

I'm designing a computer for my workplace that can intake 4K video through one of the Blackmagic Decklink SDI cards (from a Blackmagic Ursa Mini 4.6k) and record it with OBS. This machine isn't going to be running AAA games. Instead it's going to be bringing in NDI signals, while also chromakeying multiple sources, applying reaper audio plugins, etc. The video feed will also be sent out to additional confidence monitors. I'm also going to be continuously experimenting with adding multiple effects.

I'm planning to use this machine to edit the videos using programs like the Adobe CC and Resolve & Fusion. In some rare cases, I might ask it to capture running some of these programs while also recording 4k inputs. (Although if that proves too difficult, I might downgrade the incoming footage to 1080p.)

I'm also aiming for a quiet build, since the computer will be located in the same room as the camera, and in some cases may be within a few feet of the talent.

Why I'm not Building it Myself:

Unfortunately, my workplace has forbade me from custom building the rig from scratch. Therefore, I'm going to use Digital Storm as a vendor. I can presumably add and drop out some parts myself (or have our IT do this), but the overall build (mobo, cpu, chassis) has to come from Digital Storm. I'd actually like to stick in a SC2 1080ti instead, to guarantee it doesn't kick on too loudly, since it'll be in the same room as the talent.

I also have an HP quoted build here: Intel 6136 Xeon, QuadroP4000, (more details upon request) for $6625.68 (That I think is wasted money & it is actually over budget, but if anyone can point out a hard flaw with it, it would be appreciated.)

Build & Location:
My budget for the computer is $5000 US, but I'd like to keep it a little closer to $4000 so we don't have to go too far over that approved money for the capture card.
Aim: 4k OBS capture & proper studio live production
Monitors: 3 monitors at 1080p, 1 feed goes to a splitter, 4 would be nice.
Peripherals: No peripherals
Why: We don't have a computer that even comes close to the specs needed.

tl;dr

Point out any problems you can see with this Digital Storm build for recording 4k OBS feeds from a Decklink card taking in 4k, that is meant to be a live production studio that pushes OBS to its limits while being as quiet as possible.. https://www.digitalstorm.com/configurator.asp?id=1780751
