Hey everyone! I'm looking to set up a Kubernetes cluster at home using single board computers, aiming for a 4-node setup. I've considered the latest Raspberry Pi models, but they're currently pricey and hard to find. What alternatives would you recommend for building my cluster? Thanks in advance for your suggestions!

Mini PCs could be a solid option! They're compact and powerful, fitting well into a home setup. Do you have any specific models in mind?
I've been using Turing Pi with RK1 compute modules, and it's been working really well for me. They’re a bit unique compared to typical SBCs, but definitely worth considering! Check out their website for more info.
I’ve got a few Atomic Pi single board computers in my cluster. They’re quad-core with 4GB RAM and have an SSD built-in. If you can find them, they're not too expensive and should work for your setup.
You might want to look into old HP ProDesk mini PCs. They’re available on eBay at great prices and can be perfect for your needs! Plus, they usually have enough power to run a few nodes.
Consider upgrading an old PC or laptop instead. Get one with at least 16GB of RAM and install virtualization software like Proxmox or KVM. It's likely to be the cheapest route. Remember, while setting up K8s, you'll need a minimum of 3GB for one master and 2GB for each worker node if you're planning a 1-master 2-worker configuration!
