My question is: What happens if I open the SG 105 and replace the HDD with SSD (which I prefer for reliability, it will be an enterprise grade SSD) and upgrade the RAM to 4 GB (for future-proofing)? Can I reinstall and have it keep working as an appliance? Similarly, what happens if the HDD crashes, can I replace it with one off the shelf or do I have to wait for a replacement from Sophos and go without a firewall?You would lose support and warranty by modifying the hardware. The hardware installer ISO has a built-in hardware check and if the wrong hardware is detected for a model of appliance, the install will abort.

I have an SG105.
I want to upgrade its memory from 2 to either 4 or 8 GB.
I understand that opening it will void warranty etc.
But if I am okay with that, will the OS detect the hardware change and disable anything?
Or this "hardware ISO" that you talked about, has the capability to check for hardware compliance only during INSTALL?
Hi, Terri, and welcome to the UTM Community!
I don't think anyone knows the answer to your question. If you are a home user, I suggest selling that SG 105 and installing on a used PC with at least 4GB of RAM, 60GB HDD and the fastest processor you can afford.
If you are a business user, speak with your reseller.

Hi Terri,
The old UTM110/120 you could upgrade the HDD, but not the RAM (max was 2Gb for the 110/120).
Bob's Suggestions is best, get another pc, or maybe even a Hyper Visor and run them both as virtual, organise a Passive-Active HA setup, then put in a small UPS, and voila, simple solution, and only one license to pay for the UTM.
I think the UPS will be bigger than the UTMs ... lol
you can only account for between 90-95% of situations, that require redundancy/resiliency, unless you throw more money at it.
Hope this helps
