so i ordered my raspberry pi 3 b+ and it should be arriving soon but i have some questions. i got this fan and heat sink (https://www.amazon.com/gp/product/B07C9H9LJN/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1) and I was wondering, would the base case still fit even with the copper heatsink on the bottom and the other 2 on the top? I also made a quick appendage in fusion that (i think) should fit the fan (30x30x7mm) in a way i like, and I was hoping to get some advice to see if it would work (see image). i would appreciate any help and also this is a great design :)
