LF I'm not sure and really hoping none, but it stands to reason that they can't just go on forever. I'm hoping that someone has raised the issue and maybe answers are available. If the water out lives the pump great then how long can the pump run till average failure time? If the water can slowly evaporate via hose or fittings then how long till it's a good idea to change out or re-charge with fluid?
The point is, there is no way to maintain the sealed units short of replacing the TIM. Although air may not cool as well, the only thing one normally has to do to air, other than replace TIM, which shouldn't be needed in only two, three, or four years, is to blow dust off the fins as needed (and one also has to do that with the radiator(s) of water cooled systems).
Looking at the pics on Neweggs website, it looks like the hoses have pressure clamps on them with a simple phillips screw holding it together, and a drain plug in the radiator. It is meant to be expanded if you choose to, so there would have to be an easy way to drain/refill the unit.
It's not as sealed as most of the units we use.
The 240l has two fill ports on the radiator so you can bleed air in any mounting position. The pump is different from the fixed rpm pumps found on the other Cool Master water coolers. I have a 100i still in the box and I may sell that and order a 240l and run a loop to my 7950's. I was considering doing that with the 100i but I'm not sure it's pump can handle the extra flow requirement. The 240l's pump is the big difference that sets it apart, basically a rebrand of the Swiftech H220.
ETA: ordered
ETA: The Rad has a single 1/4 fill port, swivel fittings, looks very well made.
