Question i need help picking a 420mm aio for my build

[flyaway1999]

hi, im currently in the process of building my pc. im building in a dynamic evo xl white. i'm also waiting for the 9950x3d to come out to finish it, but im buying all the other parts in the meantime. I already got 3x140mm lian li tl fans for the bottom, 3x140mm lian li tl fans for the side/front and 2x120mm fans for the rear. Now, im looking for a 420 aio for the top. I have a gigabyte x870e extreme ai top motherboard and the heatsink for the m2 from what i read in the arctic compatibility list blocks the pump for the arctic iii. I know there arent that many options in terms of 420 aio's, especially in white which i would prefer but ill settle for black if thats what i have to put. Ideally, something Aesthetically pleasing as well as performant. Does somebody have any suggestions as to which i should get based on personal experience? seems in terms of white its either arctic liquid freezer iii or thermaltake TH420 ultra v2, except i cant find any good reviews on the thermaltake unit. I've also heard of some people mounting the arctic iii upside down(with the tubes up) but I dont know about that either maybe thats an opion too. does anybody have any experience with the reverse mounting or the arctic too?I also thought of maybe getting the alphacool eisbaer aurora pro 420 as later on , i eventually want to do a custom loop so i could add it with keeping the radiator too but the reviews for it arent too convincing. I'd like to know I'm open to any suggestions.

Thank you
