one of my concerns at the moment is having the Tuniq in the Antec 900, I've read that people can't get a fan on the side with the Tuniq Tower?
I've heard the same...you have to shave off a little bit of the corner of the side panel fan or something like that. I'm getting it (the Tuniq Tower 120) anyways (I also have the Antec 900).
Either that or the Zerotherm Nirvana, I've heard good things about it as well.
