Streaming PC Recommendation

I could use some help with my church trying to run OBS.

Their computer is a middle-gen i3 ( I think quad core) w/ a mechanical hard drive, 8GB of RAM, an RTX 1060, and very few USB ports.

I think this is just too weak for what we are doing.

We now use:
  • two (2) Elgato USB HDMI Capture Devices (4k-S version)
  • a USB connection to the Sound Board (Allen & Heath QU-32) - which is both input & output of sound
  • Output of HDMI to a projector
  • two (2) Output of HDMI to two (2) monitors
  • internal recording via OBS

We also use this computer to run PowerPoint slide shows.

Currently streaming via a YOLO Box Mini. I would prefer to stream via OBS. The YOLO is not ideal IMO.

My thought is that the computer should be:
  • Ultra 7/9 or Ryzen 7/9 (Intel vs AMD) (8+ core) or an AMD AI 385 Max (8 core)
  • 32 GB of RAM
  • a reasonable SSD Boot Drive (256 or 512 GB) + mechanical HD (2TB) for long-term storage
  • RTX 3050 or RTX A4000 (the 3050 is cheaper, but I've seen some desktops with the A4000 pro-level card)
  • Enough USB 3.0 (or better) ports & a good Ethernet port for streaming

How am I for specs for the computer? I think this is likely a new computer, as trying to upgrade the old one is likely not to be cost-effective (RAM & SSD prices).

On a weird side note, does it make any sense to have a second computer do part of the work (like a MiniPC, Ryzen 5 or 7 -based, likely) of video streaming and keep the old computer just to do PowerPoint and other things? Something like this: https://a.co/d/0dANpRR1 - it has a good amount of USB 3.0 ports. The 24GB is better than what we have.
However, this would require two keyboards/mice or a KVM switch. So, I'm not sure if the extra fuss is worth it. Thoughts?

I appreciate any insights everyone has.
 
A typical church only needs to stream at 1080p30... so that RTX 1060 should be fine, if one is being careful.
For the CPU, details matter and an i3 is something I'd never recommend for a CPU intensive task (which real-time video work is)... as an IT person... I don't know what a "mid-gen" i3 is... could it work - probably, yes, IF one is careful, and optimizes OBS Studio and OS, etc... and you add some more RAM 8GB will be problematic, most likely

And recording to a HDD... which is also OS drive... not really a good idea... doable... but ... ouch. glad it has been working for you, but that is bound to create some I/O contention...
*IF* you have access to some spare parts (without buying and possibly wasting money), I'd be inclined to try swapping out HDD for a SATA SSD and upgrade to 16GB RAM. Then some OS optimization ... and then test... you might get a little more life out of the PC (or not).

Things you need to clarify
- what resolution? do you plan to stich with a (presumed) 1080p30, or do you want something that can handle 4K?
- Yes 32GB RAM is desirable, but you might be okay with 16GB RAM ... depends on level of OS optimization and incoming camera feed impact. The House of Worship I sent up many years ago is still running multi-camera on a i7-10700K , 16GB RAM, and 1660 Super... runs fine. And PPTx windowed slide show for service bulletin.. Recording set to record at about 3X bitrate of streaming for high quality sharing of wedding, baptism, etc.. type content.. Recording to OS SATA SSD is NOT a bottleneck (with optimized OS).

Personally, I set up a single computer, and managed it professionally. in my opinion, easier than managing 2 PCs... but it depends. I set up a dual monitor setup, and with adequate training, 1 person can run the whole thing... but it depends.
