Dell OptiPlex 7010 uSFF
These days it is very easy to find offers for cheap, refurbished office desktop PCs. I chose to build my Kubernetes cluster with Dell OptiPlex 7010 uSFF machines. This is a small yet very high quality machine and can be configured with up to 16GB ram, more than enough for a Kubernetes node.
I bought four machines from Levna PC. Despite being refurbished the machines I received look almost brand new.
I additionally upgraded some of the machines with leftover RAM scavenged from old, dead machines, and the DVD drives were replaced with a caddy that holds a 320GB HDD.
