Questions about Zotac Zbox Ci323 Nano

Depends on the settings in the BIOS, but yes, it works, because that's how I do it. Now I just have to find out how to deactivate the annoying beep when switching on. It almost wakes up the neighbours...

I use it as a pfsense firewall/router with fibre7, but I don't achieve more than 600Mbit/sec out-of-the-box, but maybe with a little optimisation I can achieve more...

No harddisk, no RAM. Everything else is builtin

I have the ZBOX as a firewall (Sophos) in permanent use. Together with this memory, I have absolutely no problems! HyperX Impact (2x, 4GB, DDR3L-1600 (PC3-12800), SODIMM 204)

Sophos UTM as well as Sophos XG work perfectly. Do a BIOS update! https://www.zotac.com/de/files/download/mini_pcs?driver_type=238&m_pcs_series=All&m_pcs_os=All&sku=ZBOX-CI323NANO In the BIOS, the boot mode must be set from UEFI to Legacy, otherwise there will be problems with the Sophos software. Only needs 7-8W in firewall mode! I previously had my UTM on an HP MicroServer that consumed just 40W. I am completely satisfied! Attention - the integrated WLAN cannot be addressed by the UTM/XG. Only the 2 internal RJ45 network cards can be used. Have fun with it!

That's what "passive cooling" is all about ......

Speed Fan reads the temperature data incorrectly depending on the motherboard. In addition, it cannot be that the CPU temperature gets so high, because the processor automatically starts to throttle the power at max 90° or so, in order not to exceed a specific temperature limit. So you should not worry. Otherwise, you can verify the temperature measurements with other programmes, e.g. "CPUID HWMonitor", or "Core Temp". Hope this was helpful.

No, I have also purchased the following: RAM: HyperX Impact (2x, 4GB, DDR3L-1600 (PC3-12800), SODIMM 204) Hard disk: Hitachi Travelstar Z7K500 (500GB, 2.5", Notebook) You can install a maximum of 8GB RAM and the hard disk must not be larger than 2.5 inches. The installation of the two components is very easy.
