I've more or less decided now on the HAF X (to replace my cosmos S - although the looks of the S have really grown on me) now.

I was/am really interested in water cooling everything (especially after checking out the specs of EVGA's GeForce GTX 580 FTW Hydro Copper 2, (instead of ordering the standard air cooled "superclocked" version) - that, and my mobo (gigabyte extreme) has water blocks pre-installed, which really look cool - the way they're designed), but the whole maintenance/problems if you have to transport the case is a huge negative keeping me away from it.

@pcgeek - I think I'll be holding on to the noctua in the mean time (just in case I decide on a different cooling solution and need it). Maybe in the future....? :)
