Like most people, I entered COVID as a normal hobby geek with a Linux server I played around with and a healthy hardware habit with a side of home automation and DD-WRT. I emerged from COVID enrolled in college, now with two servers (one new build, one rebuilt from my first one), two Pi, multiple instances of Home Assistant (one dedicated) and putting sensors on everything a sensor could go on and rewiring switches for wifi control of overhead fans, flashing every compatible router I could find on Amazon Warehouse with DDWRT in my home for an ad hoc mesh network (no, it didn't work, but I didn't care) while cabling everything to switches and creating a really hilarious network deathtrap tripping hazard, a massive media library (discovered Handbrake and making multiple resolutions) and a Sonos home theatre system. And yes, played an unhealthy amount of Animal Crossing and got an NVIDIA Shield Pro for streaming and Plex, as you do. I'm sure everyone can relate.
SBC's were the natural escalation; I had credit card bills to pay off and that's going to take a while.
I gatewayed with Pi like ten years ago but it took off during Later COVID when I noticed my credit score and started testing it as a NAS, Media Server (later: Cassiope Media Server, my second end to end Linux build), then got into learning about the kernel itself. I already had an Odroid (Home Assistant Blue) so why not go on, so project-based SBCs seemed healthy; I had a reason for buying one. This led to more Pi's--as I couldn't use Kernel Pi (Eurydice) for it and Andromeda Pi was masking my personal network, then I needed one for a Pihole (Iphigenia, Hecuba), which is how I ended up with a BeagleBone Black (Medusa) for an Open Thread Border Router. Still pretending I wasn't just collecting them like cats, I networked them together and just enjoyed looking at them and making them matching banners with figlet with the excuse I was learning how to do network-wide deployments over SSH (true) and learn Debian OS (technically, I am doing that) and started PoEing things (my credit card bills may not be getting lower, no).
The count stands at a total of 9: one (1) Pi Zero W, one (1) Pi Zero 2 W, one (1) Raspberry Pi 4B 4G, two (2) Raspberry PI 4B 8G, one (1) Odroid N2+, one (1) Beaglebone Black, one (1) PocketBeagle, and one (1) BeaglePlay. (Other: two Linux machines, Watson and Cassiope). Yes, they all have names and technically, each is associated with a project. The BeaglePlay's (Circe) associated project is 'create my own documentation on what it does because Beagles don't document'.
So which ones do you use, why, origin story, feelings: go.
(I'm moving in a week and half my hardware is being packed. I'm about to have to take down my network and Home Assistant and may be freaking out. I'm not sure I know where any light switches are here, either.)
ADHD here: I live for finding people who know how to enjoy their hobby correctly: like you're invading a country and taking no prisoners.
I am seriously feeling the Zima, but I just went over to Orbi Pro 6--yes, I gave in for Wifi 6 and no regrets, the coverage with just one satellite and the router is unreal. I'm trying to decide if I'll have time, but I really desperately want to learn OpenWRT; my first try was--well, there hasn't been a second one. But there will be. I picked up some (read; too many) USB Wifi dongles via rmorrow's list of linux compatible ones, so I could try and test drive a diy wifi router with it. God, that sounds fun.
The transcoding problem is one that keeps popping up. Depending on your price point, the NVIDIA SHIELD Pro (latest) can handle anything--and it is a genuinely amazing streamer and really spoils you for most of the rest--but that means it would only work when watching using that over Plex or whatever media server software you can put on it. And I think the X-Box? When I was researching during COVID, the only other all-in-one option was a full dedicated server with either Threadripper or something in that family; I think when I did the math, just for the processor, my minimum investment for 4K and Atmos/7.1 was roughly $600-$800 if I was lucky, and that's before the board and like, a sound system that does Atmos.
I know there were some other possible options with hardware, but it's been a while. If I think of anything, I'll bookmark this page to post here. Hopefully you'll find something you like and will work for you. I know exactly how frustrating it is finding a solution.
