No worries, I should be pretty safe.
NAS with mirrored devices, dev folders with sync to the NAS, external drives to back up the NAS.
The worst that could happen is that the 4090 blows up, there's no way to get a new one and the 5090 is a fucking joke, both in price and performance.
But IF that should happen, I still have the 3090TI
Everything else (PSU, board, CPU, ram) should be replaced in a few days.
In fact I'm thinking to move the 3090TI to a second PC to reduce the risk further (and to have two PCs for rendering), but that would increase my electricity usage to 1200W an hour while rendering with both.
Guess I need a storage for the PV first.
