Just did a test fit since I just realise I haven't test fit the 360mm rad after I cut the top panel! 


and it works! holes all properly aligned and spacings estimated/measured are correct! I just need to do some finishing for the top panel.
Here's your answer! 



It fits! Just don't go using deltas/push-pull (maybe if thinner rad can).

The space left is JUST NICE for an ODD or whatever you wanna stuff in. Also, depends on how you mod your case, you might still be able to use the top bay for something, depending on how big that something is.

OR the new NZXT Hue. 

but have to take measurements first. 
Thanks bro! the switches I got them from PPC when they were on offer. You can get them locally as well, from lamptron (ask niclasteoh/lingloong). I think limhongwoon has as well.

The ones I got are delrin blue dot LED momentary switches.

thanks!

Current running costs or cumulative? 

If cumulative then I think past 6k already. 

If current then I think about...2k? and I still have more parts to get.
