I'm in the process of updating m homelab. Threw out the qnap nas, replaced it with a homebuild nas on Truenas (4x8TB HDD, 4x1TB SSD). Replacing my ubiquity edgerouter pro 8p with a Mikrotik hEX refresh. About a 10x speedup for throughput, 20x smaller, 1/4 power consumption. Next I'll be looking to replace my edgeswitches. I can run them stand alone, so there's no rush.

I am not going to buy myself deeper into ubiquity. I'll just try to optimize for the current needs.

If you want true foss, run pfsense or opsense on your own hardware.
