I have this case which works perfectly with NV2 4Tb --> Icy Box IB-1817M-C31 - NVMe M.2 (M.2 2260, M.2 2242, M.2 2230, M.2 2280, M.2)

Kolink KO-M2UC31 externes Gehäuse für M.2 NVMe SSDs (M.2 2260, M.2, M.2 2242)

I just installed the 4TB version in an Orico enclosure, the dirt-cheap transparent type. So far it seems to work well.
