I'm new to Docker and just bought a $189 PC specifically to experiment with it. The plan is to install Ubuntu on this machine. My main question is: can I access this PC from another computer remotely to play around with Docker? I'm mostly a Windows user, so what would be the best way to set this up? Should I use SSH, a domain, or something else?

Consider installing Proxmox instead of Ubuntu. It’s easy to manage via its web interface, and you can use community scripts to get Docker running in a VM or LXC, which keeps it tidy without needing physical access often.
If you're experimenting with Docker, you could also try it out on a Raspberry Pi first if you have one. They're quite affordable and perfect for testing before moving to your new PC.
Once you get the OS running, SSH is the way to go for accessing your home server. I personally prefer Debian over Ubuntu, and there's a guide for installing Docker on Debian which works on Ubuntu too. Check it out for details!
For remote access, SSH is reliable for local networks. If you want to access it remotely, you can connect through a domain using Cloudflare or Cloudflared. Just set up your network correctly and you should be good to go!
Absolutely, you can manage Docker remotely! First, install Linux and add OpenSSH to your setup, especially if you plan on running your Docker machine headless. Then, make sure to install Docker—avoid the Docker Desktop version on Linux, as it's not the full engine. Also, consider using Portainer to help manage everything through your web browser. You'll find it super handy!
You might also want to look into installing Proxmox on it. It makes managing VMs and backups a breeze!
Go for a lightweight Debian install (no GUI), enable SSH, and install Docker using the official scripts. Dive into Docker basics through the command line first, then look at Portainer if you feel comfortable later. Also, consider Tailscale for remote access!
I think it's totally fine to use tools like Portainer while learning. It can keep you engaged and motivated!
That PC should handle a lot! I have a similar Optiplex but with only 4GB RAM, and I run multiple services like Pi-hole and Plex with ease.
