That is true, you're also less likely to find a healthy person in a doctor's office
H100 isn't that bad after all, unless you get one that's rattling or has a defective fan controller. Right now all the H60s, H80s and H100s you see in shops are the "old" ones, the new "fixed" units without the shaft/bearing issue aren't widely available yet AFAIK.
These coolers have the advantage of being sealed, so they are maintenance-free until they die. In a custom loop you have to remember to watch the coolant level and you have to take it apart roughly once a year to clean it up and change the coolant.
Other options for sealed system are the Antec Kuhler 620 and 920, both 120mm (I'm not sure however if the 240 rad in H100 provides any significant advantage, IMO the pump is too weak to fully utilize its (RAD's) potential). And that would basically be it, Antec's are the only ones that have an established position on the market, apart from Corsair's.
