I am going to try out your pihole container now. This is a very cool feature, if it means we will be able to do the same ourselves. I will say Turn key has more than 100+ applications they have been finetuning for more than a decade, and have other niceties such as backup to S3 and other features built in. Adding them is an easy win for you not having to support all those apps. Turnkey is based on Debian Stable, and they provide support for their installs. The apps they provide are less for home use like pihole is, and more for business and work related things. Wordpress setups, CRM, Storefronts etc. They are great to practice on as a dev environment before pushing them to a live server. I think they would be orthogonal to what you are doing. Anyway, thanks for looking.

Turnkey is a set of custom Linux Distributions that are set up for specific usecases. Each use case gets its own installer, such a a Wordpress server, or JS dev stack or MySQL server or a LAMP stack. Turnkey has both baremetal and LXC instances, and Proxmox includes the LXC instances for use in their system. Proxmox uses their own custom branded LCX and do the work to make them work there. https://www.turnkeylinux.org/ They are siimilar but orthogonal to the Bitnami style APP/USECASE focused setups.

I don't think those use nesting, they use the jit to run code. Nesting is for the same system arch only, so x86-64 int the case of Unraid.

If you are looking to find Server boards for old CPUs, look at reddit's Home Lab Sales. It is essentially a marketplace specialized for exactly that. You can also use the labgopher tool made by some of the folks on the HomeLab Reddit that scrapes eBay for some popular servers that can use those parts. Browse their wiki to find links to Government auctions, and other trusted suppliers for older tech, if you don't want to risk trading on Home Lab Sales itself. You can also look at ServeTheHome forums for sell buy and trades. They tend to find great deals on HDs and really overkill tech like 4U Supermicro Servers like this beast that can use 4x E7 v2/v3/v4 CPUs, supports up to 12TB of DDR3 or DDR4, and has 4x PCI-E x16, and either 4x or 7x PCI-E x8 slots depending on how you populate the memory. The chasis supports 24 3.5" SAS3 12G/SATA3 6G drives. Here is an eBay listing for it, with 256GB Memory. Have fun going down the rabbit hole.

@ChatNoir True, you can lose a few frames, but that might be a small price to pay if you are streaming and care about interacting with fans or with other streamers you might be streaming with. It does take some memory, so on memory hungry games you can experience fps drops. This is a great setup if you aren't streaming, for applications outside of gaming like creating tutorials and other things.

How much latency does this add into the stream? One advantage of recording through the Gaming PC is the video image never has to leave the GPU before it is trancoded.

+1 for iSCSI. Have you considered just compiling it into the kernel, and letting the community create dockers for it? This would give you some idea of how it would be used in the real world, and how used it would be.
