V6 hot end, Petsfang cooler, and lights. I did have to slot the z-stop bracket to lower down due to the shorter gantry to tip distance. Now I can print 450mm high. I weighed all the parts from the old and new setups, new assembly is 4 grams lighter. The stock sheet metal hotend box is quite heavy.
You could also run the stock hot end in the new cooler if you want, it does fit.
