I am using the PC as an iSCSI/NAS Target Device for my development Environment. For that usage the PC is perfect. Systemload, Tranfer Rates with Multipathing a.s.o.
BUT:
There was way to much thermal paste on the CPU, really way to much it was allover arround the CPU as well. After Cleaning and proper reaplying this was fixed.
The other thing was the 3rd NVME Slot which was dead on arrival.(bend out)
