If you want good and light ones there are plenty but obviously it'll be a lot more expensive

U were refering to casing more than 1k bucks? I can only think of the TJ07 and the Obsidian 800D. Cheaper one would be the PC-A77.
As for the TJ07, I'm not sure whether thick radiators (thicker than Swiftech MCR)can be fitted on top of the casing but as for the Obsidian 800D, I'm pretty sure it has no problem of doing this.
Talking about radiator fitted on top of the casing, which is the better orientation of the attached fan(s), pulling outside cool air into the casing thru radiator or pushing hot air of the radiator away from the casing?
Since hot air raises, I would personally think tht the second does make more sense despite this might lower the efficiency of the radiator since it should be blown by cool air instead of hot air frm the inside of the casing.
But consider at the ambient temperature within the casing of wc setup is not as high as hsf cooled setup, I mean no heat exchange process being done inside the casing, how hot would be the temperature inside wc cooled casing?
What could be the efficiency difference on the radiator between this two ways air flow orientation?
