You nutters I get it, it looks really nice and performance is top notch. Understandable too if you have a loop you've built up over time and you're only changing blocks with each upgrade... But from my perspective it's just not worth it, there's no real performance gain for the outlay for me.
It only became that much because I choose to do a complete new loop build with new rads, pumps, controller and hard tubing. I could have just bought the block and fitted it into my old loop.
