It doesn't seem like we have enough opinions in this thread, so I'll throw mine in too.
-Agreed with a lot of the others above, having Rookie and Novice seems redundant -> merge these two into a single Rookie league with a time limit of somewhere between 3 and 12 months(maybe 6 months would be a good number)
- From what I've seen, the biggest issues with cooling come from mods having to define a line between ambient water and chilled water; I have seen few/no accusations of people in Apprentice running LN2, it's usually pretty obvious from clocks. There's also a clear separation in expense and complexity between sticking a radiator outside/in a bucket of ice vs. SS/DICE and colder. Anyone can do the former, jumping to the latter shows a more serious commitment to OC. This lends SS and colder as a good starting point for the Extreme league.
- OTOH, there's also a reasonable argument to be made that SS/DICE is substantially cheaper for most people than LN2/Cascade. That would make "colder than DICE" the other possible cutoff for the Extreme league. Personally, I think the SS cutoff makes more sense, especially since anything warmer is much more achievable for the "average" user, but I wouldn't have a problem with either one. Either way, I think chilled water setups should definitely be allowed in Enthusiast.
- I'm in favor of having an Elite league, even ignoring the question of binning, having access to ES BIOSes, mobos, software, etc., along with an easier time getting technical questions answered, does seem like a substantial advantage to me. In the end, I don't really care though, I wouldn't be heartbroken if Elite was merged with Extreme. Just gives me another excuse when I can't get first place a reason to push harder.
