Plenty of teething pains with LUMI sadly. Maybe some day it will be reliable.

My point is that OP can not just pick any mining rig and expect it to work. Mining rig chassis are designed so that you can use those USB risers that are long and easy to route. Now when you have the wide and relatively short risers it can limit the physical configuration.

To avoid taking too much advice from miners, the thing with mining rigs is that the amount of data transfer between CPU and GPU is minimal so they can get away with 1x risers, which definitely won't be a good idea on a deep learning rig. This means pretty much no mining rig would function as a deep learning rig.

In addition, 1000 cycles is a LOT. I think even the heavy users would struggle to use 1000 cycles of for example 200kWh (4x a reasonable amount of 50kW) within the usable lifetime of all the other parts of the vehicle. With consumption of 0.3kWh/mile you would need to drive over 600k miles to have the battery degrade to "just" 100kWh, which still means 300 mile range.

If you take the 4x capacity, lets say take a 300 mile current battery, now you have 1200 mile range. If we take 1000 cycles at 50% capacity it is 600,000 miles, way more than the vast majority of cars last, and you still have a 600 mile range. 1000 cycles is a lot and barely any battery goes through 1000 cycles in consumer use.

EDIT: With the 100k mile warranty you are barely reaching 100 full charge cycles so if we assume linear degradation the battery has degraded by just around 5%, which would be reasonable amount for any current EV to degrade within 100k miles.
