I'd open the box and make sure the fan isn't making the noise because it's stopped spinning lol. I have ordered one for mine if it fits I'll post a link to the eBay listing
+1 my exact thoughts.
It sounds like a few people are going to the Darkside and considering P2000. I think that's great as most know I'm a fan and its nice to hear some positive stuff than the usual thing like it killed pinball etc etc.
Hope your RFM gives you months/years of pleasure but maybe lay off with the banging
