I just drilled a hole for a 3/4 inch bulkhead in the back of a Nanocube 6. I used a Dremel diamond bit that I bought at Revy for $15. I built a Plasticine dam filled with mineral oil to keep the bit cool. It took under half an hour including setup time and was a lot easier than I thought it would be.
