Pros and cons of streaming PC setups
- Optimal gaming performance
- Optimal streaming quality and performance
- Easier to include a VPN in non-gaming workflow on the SPC
- You can turn your VPN on and off for specific games and environments on the GPC
- GPC can reboot and crash without ending the stream
- Without NDI (see below), you have to route GPC output through a capture card1
- With NDI, there can be plenty of issues
- Requires an elaborate wiring and audio setup
- Audio over Ethernet (see below) can address some of these issues
- Without NDI, you have to do a full monitor capture of your GPC
2pc setup with NDI
With one Ethernet port on both; each line is an Ethernet cable:
Router / \ Gaming Streaming
With two Ethernet ports on the gaming PC:
Router - Gaming - Streaming
Remember that you can always just buy another Ethernet port over PCI-e instead of getting a motherboard with two ports.
Your CPU must support instructions for
Your gaming CPU will also be put to work slightly when you send your output via OBS on your gaming PC to OBS on your streaming PC.

I see a lot of people have issues with NDI for whatever reason. I’d advise against buying a streaming PC for the purpose of NDI streaming since there’s a risk it might not work for inexplicable reasons.
A recurring problem I see is people who “don’t have true 60 FPS”. Make sure this is a resolved problem by the time you give NDI a shot.
We all know what it’s like to have issues with free software we depend on for streaming with OBS Studio, but with NDI, there’s the additional aspect of hardware-specific issues.
Virtual audio over Ethernet
While your at it, you can also cut out a lot of audio hassle with mixers and whatnot by sending your audio to your streaming PC over Ethernet using VBAN. Here’s a quick how-to video:

In order of size:
Intel’s Hades Canyon:
NUCs aren’t cases but complete computer builds except your have to get the RAM yourself. One obvious reason the DDR4-2400 RAM don’t come with the NUC is that DDR4 prices are all over the place right now.
NUC are an all-in-one solution, which greatly simplifies buying and setting up the computer. The downside is of course that you can’t upgrade and customize them.
Console form factor
Mini ITX covers many sizes, but I am partial to those with a console form factor such as Fractal’s Node 202 (w/ PSU):
Cube form factor
Other mini ATX designs are cube-like; most are designed as small desktop PCs rather than something with portability.
