Corsair H50 mod question

[shinester184]

I know a lot of people do res mods with their H50s, but I don't see it as a great idea as surely the pump is underpowered to push that much water round....If I was to have a corsair H50, could I simply replace the pipes (for clear) and the coolant to give it a more customised look? Or what it be a real nightmare to fill/bleed? Not seen one in person so not sure what the accessibility is like

From what i've heard from my friend is very tricky and hard to change coolant.Too many things to unscrew undo.But is duable,need some patience.
