As a tiny autodidact project I hooked up a cluster of three old Asus Eee PCs for experiments with ansible and kubernetes (and potentially Hadoop and HBase later). In my tradition to name computers after StarTrek characters the computers all carry names of medical officers: bashir, crusher and mccoy. All have 2GB Ram - the maximum capacity for the Eee PC - so that probably limits the setup to educational purposes.
Adhering to chronological order McCoy is also the oldest of the netbooks running an Intel Atom N270 processor with no x86_64 instruction set so some packages cannot be obtained precompiled but need to be build for the i386 architecture.
Bashir, being the youngest, can be burdened with the additional task of serving a common home directory for the cluster (via NFS).
