how about dual DDC instead? 1.5kg of brass or 400g of plexi . the dimension on the product page is wrong, it's not 40mm thick but only 25mm thick per manual. on paper it should fit hahahaFor science! I've pressure tested the spare 1U ES I have (because with alpha cool, you better have a spare), and that's fine at 0.5 bar.
On a side note! I've test fit the alphacool dual DCLT plexi and this should fit. With pumps attached, it should be total 35mm thick. And it has RGB so there's that (can also be removed).
Unsure why imgur rotated this..
