I was looking into lighting the main case area but realised fans could also be used so sourced a 25mm spaced PA120.3 (£30), this will be going into the roof coutout and have some AF120's on it. Temps and noise are fine but it seemed a shame not to use the cutout. Have also got an LED for the reservoir and some more hose coming. Wish I had some more cash and I'd make the move to solid tubing, next time hopefully.
