Yes, NUCS have the worst heat dissipation ever. Especially if you decide to use M2 drives. I have seen them burn out those drives (even with the cheapo heat sink on the m2 drives) quick. I have also used the Lenovo's mini pcs and the same kind of thing, heat killing ssds and hard drives in general. My suggestion: Build one yourself with a third party case though good luck finding a decent gpu for a good price due to those crazy miners.
