Building Blender Workstations and Renderfarm...

Has anyone had any experience building their own system specifically for Blender? I’m mostly interested in consruction of a mini-renderfarm for Blender. (Possibly a dual Opteron server.) Has anyone had any experience with setup of distributed rendering with Blender?
