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
It's getting up there in years but I'm running a Dell T5610 with 128GB RAM. Once I start my new job I might upgrade cause it's having issues running my MC server.
