Passive, Aggressive Cooling
Behold the MonsterLabo, a large heat exchanger with enough free space to install computer components in. The heat exchanger is capable of cooling a 100W TDP CPU along with a 120W GPU passively, or with the addition of a 140mm fan you can handle TDPs of 140W and 160W respectively. There are also size limitations, you will need to limit your choices to a Socket AMD AM4 or LGA115x CPU; for the GPU you can consider an RTX 2070 as the limit, with the stock model’s 175W TDP.
Kitguru tested the enclosure with a Ryzen 7 2700 and RTX 2070; but you could choose to purchase a fully configured system as they offer a AMD Ryzen 7 and GTX 1660 Ti model as well as an i5-9600K and RTX 2070. Kitguru tested their build in a number of configurations, even the worse case scenario saw GPU and CPU temperatures well under 60C at full load. It will cost you a bit, but if you are looking for a unique looking, completely silent case, this is worth a peek.
Picture the heatsink used in, say, a large be quiet! cooler and then imagine something five times larger and you have a starting point for The First.
