I am thinking how to best utilize the space on top of my PC for a radiator. I don't mind moding it, as long as I can cover the mod with the top cover seen here.

I have a 190mm x 320mm x 40mm space as measured in the links.

I was thinking pro's vs con's:

180mmx180mm = 32,400mm^2 I could do this by adding some screw holes and use either the "200mm" fan that comes with the case (seen in the pictures) I've heard these jumbo fans are not good for rad cooling. I may also be able to squeeze in a tiny 80mm next to it.

280mmx140mm = 33,600mm^2 This would require the most modification (cutting out a hole directly in the middle of the top of case) but I could use 140mm fans which I've been reading are better than "200mm" fans the case has on top for moving air through a radiator

240mmx120mm = 28,800mm^2 This requires zero modding the case is designed to hole this size radiator.

I estimate having about 450 TDP if these calculations are correct. I also could add 1x140mm rad in the back which the case is also designed to accommodate.
 


I know I would personally keep within the pre-built dimensions of the case. You won't be getting a huge amount of extra cooling to the CPU from modifying.

 
40mm is not a lot of room to mount a radiator inside the case, it will restrict you to certain size thickness rads that may not give you the end cooling results you would want to water cool in the first place?

What clearance do you have underneath the top cover?

Note: FYI Fans in the size range of 200mm sound impressive, however those size fans are more for a mass of airflow and not concentrated, we are just now getting some serious airflow in the 180mm fan range, but the 200mm is just not there yet.
 


Water cooling for higher overclocking can be a waste of money and a frustrating gut punch for you, if you do not have the radiator cooling field to get the job done!

Since you have already said you don't mind modding it, I suggest you think outside of the box and not just be restricted to what the case offers, because that case is not a very efficient design for internal water cooling.
