I'm planning to buy everything(RAM, Mobo, case, psu etc) from your website, but I'm unable to find an elevated multi-tier rack which is large enough to accommodate the case.
Could you recommend a rack on which I could place one of the 4U cases on each tier?

YouTube, Reddit. That's where all my time goes. Every. Single. Day.

Ha ha, for real?

But my most overvauled coin is Ripple. Shouldn't be anywhere near No.3 on CMC imo

jillscarbrough did measure the TDP, but that's only how much the cooler must be rated to dissipate. Based on these benchmarks-

The RX 470 and 570 pull 340W. Combine that with your CPU's TDP of 84W, that amounts to 424W. We haven't even took into account the RAM, HDD and risers.
These combined will go over the rated efficiency limit of your PSU, and can lead to unexpected crashes and shutdowns. I would recommend getting a 750W or higher PSU from your local market as well.
