Rehabilitated HP z440 workstation, checking in! Popped in a used $20 e5-2620v4 xeon CPU and 64gb of RAM and it sails for my use cases. TrueNAS as the base OS and a TalOS k8's cluster in a VM to handle apps. Old but gold.
Interesting, I haven't had any issues with things loading with mine, maybe it's your adlists causing issues? Try disabling some, there might be false positives in there giving you issues
