I know I'm very late here and haven't read these forums much at all. Given that, watching the recent videos on machining equipment really made me interested in what the future in terms of LTT videos has in store. Namely, looking at waterblocks, can you do better with an extremely custom waterblock compared to a "stock" 3D water cooler? Comparing things, like machining it yourself and doing a professional 3D SLS (or similar) job is interesting also.
