Gigabit ISP builds at different price points, wattage, and performance (inside!)

Wow, no mention of the $120 3.6ghz quad-core i3-8100?

You are absolutely right! Let me add it. Thanks!
EDIT: After adding the new entry, it seems the choice optimally comes down to either:
$395 - Core i3-7100T Build (35w) [ 5168 | 1930 ] {2-Core}
or
$475 - Core i3-8100 Build (65w) [ 8177 | 2092 ] {4-Core}I wish the i3-8100T was out. As far as single threaded performance is concerned, I would choose the $395 i3-7100T @ 35w over the quad. As far as overall bang for the buck, the i3-8100 is definitely both the deal and performance sweet spot - though 65w is hefty for my tastes. Still undecided!

You may want to focus in U and J series builds. The U-series i3 and i5 setups often have about 15W under normal load, even less when idle. Comparing a 15W build to a 35W model is more than twice the power cost while not really getting you much more in terms of performance or options.
Also, keep in mind that upgrades are rather rare. Most often people will add in some RAM or a bigger disk when they want to do extensive logging or maybe add IDS/IPS packages. The CPU and NICs are often untouched from the initial setup unless there is something like a bandwidth limitation based on the NICs themselves (sometimes people will add a 4-port GbE NIC and put it in a LAGG with a managed switch for faster inter-subnet routing and firewalling).
Any embedded build that has a fast enough CPU with room to spare, and already has at least two Intel GbE NICs will probably do as long as you can install anywhere between 4GB and 16GB RAM and have at least one SATA port with at least 3Gbit bandwidth (SATA2). It's when you are going to do line-rate Suricata or Snort where you have to get some really special attention to the main board and CPU.

Keep in mind that the Thermal Design Power given in Watts for each CPU does not indicate the power consumption in comparable conditions. It shows you what size heatsink/fan you will need at maximum load.
If your cost calculation includes a 30W electricity consumption reduction between a T and non-T variant in an always on system you will be paying more than you think. The actual power consumption of each doing the same work will likely be far closer.

yeah, the main difference between a low power chip and a regular chip is that the low power chip is throttled and can't run as fast. at idle, they're about the same. the only reason to care is if you're designing a system than can only dissipate N watts and you want to make sure the TDP never exceeds N.

Ah yes, that is true. Especially post Core2Duo-era.

Isn't the 7100 and other of the new ones prone to the HT bug, if the bios isn't updated ?
If yes , make sure to get a MoBo where you trust that Bios updates will arrive.I know i dropped a chinese i7 (esxi playtoy), because i didn't trust the Bios was new enough, or ever getting updates.
Now i'm considering an i5 NUC w. 32G Ram instead (Ought to get updates) , but has a FAN :-

https://www.cpubenchmark.net/cpu.php?cpu=Intel+Core+i5-7260U+%40+2.20GHz&id=2993I wish the Qotom i5 would take 2 x 8G , then that would prob be enough for an esxi beginner.

Are you cooling the CPU with a heatsink? Is that included?I forgot that CPUs come with a stock heatsink. Whoops!

Any suggestions on how to find U compatible motherboards? For instance, when I search for "i3 7100u" the only results I get back are for a couple laptop motherboards which cost close to $200

That is because those pretty much are laptop CPU's. You won't find them on standard motherboards, pretty much only on embedded and industrial stuff, or the Qotom and MiniSys boxes we already mentioned. There is a small number of ITX board that have them as well, but I have no idea if Intel even allows people to buy they SoCs to put on motherboards with PCIe slots for example.

What about the LAN NIC types on these mini-pcs? For example, I've seen quite a few threads discussing how bad RealTek LAN adapters are for pfsense. This thread is a good case in point:

There is no mention of what kind of LAN NICs these boxes have in the tech specs, so it's hard to know if they use stock Intel, RealTek or something worse.

The boxes in the Qotom thread all use Intel cards. Mostly the I2xx series.
