    First off, great bios! Overclocking, voltage, power stage options available; will use for undervolting for sure! Very surprised and delighted to see this.The bad: The CPU (i7 1165G7) was HOT. I removed the board (very easy; 4 screws) and the aluminum heatsink has a copper slug screwed onto the backside for contact with the CPU. Unfortunately there were two oversights:1: The thermal paste between the copper and aluminum was minimal. I cleaned it off and re-applied my own thermal paste.2: The BIG ISSUE was the CPU didnt TOUCH the copper heatsink. There was a huge gap with a giant ball of thermal paste which meant almost instant thermal throttling. I used some .5mm copper shims and that fit perfect. Temps are still high; idling into the 50’s but a lot better than before. I plan to do some undervolting and power limiting and hopefully temps will be manageable.Overall it loses 1 star as the fix was easy and took about 10 minutes.

    Apparently there are two models of this same device one with a dingle DIMM slot and a newer one with a dual DIMM slot. I received the 2 slot unit. The RAM specs don’t say that we need 1GB packages on the module, but the seller warned me of this as I bought a barebones unit and they reached out to me before it shipped. Apparently it won’t post with some 512MB package DIMMS. However, I ordered A-Tech 16G (2x8GB kit) which advertises it ships with 1Rx8 and 2Rx8, so I took the gamble as I couldn’t find anything else that ships quick and was cheap without looking too shady. Well, it posted fine and pfSense recognized the 16GB of RAM and the i225V NICs without any drama.I will say that speed tests show around 690Mbps at 15% CPU at peak through this unit with my provider. I don’t use IDS/IPS, but I am running 4 additional Vlans, maybe two dozen firewall rules, pfBlocker, and a few other tiny packages. It idles at 2% CPU with 5% RAM used. I am using a Motorola modem with a 2.5Gbps NIC, a Unifi 2.5Gbps switch and a desktop with a 2.5Gbps adapter.This could just be my provider Cox Cable (Docsis 3.1). If I plug the computer directly into the modem I hit 940Mbps. This could be me needing to tweak my configuration, but I am not willing to shell out $930 for a Netgate 6100 to find out.I have a Dell Precision with an Intel i350-t4 adapter that I tested pfsense bare metal and had similar results with this line.All in all, I am happy as this was very cheap and uses very little power.

    Received the first unit, had some issues installing an OS on the system. Crashed during boot, crashed during install, never would complete install. During troubleshooting it was found that the RAM was bad. Reseating the RAM didn’t help, unit was received DOA.Contacted support, performed some verification troubleshooting with them (Time zone differences were a bit of a pain, but not unexpected) and received a shipping label to return the dead unit and a new one expedited to me.New unit arrived, tested out and has been working perfectly for over 24 hours. Solid, well built and a nice compact form factor make it an easy choice should I need another one.
