I had a minor brainwave to reduce the power consumption of my home server. Take out the GPU and use the on-board GPU. This was only recently made possible by the fact that I changed my monitors and the new ones have VGA connectors as well as HDMI and DVI. Something I had failed to connect with the possibility of reducing the home servers power consumption. The upshot is that I would be unlikely to recover the cost of upgrading it to newer parts for a long time as its power consumption is like to be pretty close to any upgraded kit.
