  • Aa key trait of RFID is that it’s passive and only has a range of inches to maybe 5 feet. Even mmWave towers are typically out of that range, plus it needs active power. Tracking someone using their (actively powered) phones cell signal is incredibly easy, even with 4g. It’s shifting through all the data that’s hard and time consuming.

    Identifying someone using 5g’s radio frequencies would technically quality as Radio Frequency IDentification. When people talk about RFID they’re typically referring to those passively powered key cards. Those key cards barely work when they’re an inch away from the object, let alone 5 feet away plus 0.5 cm of RF absorbing skin.






  • There’s a decent supply of not humongous mATX cases with decent drive options. I found the JONSBO N4 which looked neat, but then saw this reddit thread saying it’s kinda poopy (but see the top comment for a fix). But fancy features like hot swap bays make them pretty expensive. If you don’t want hot swap there’s a ton of mATX cases with 4 drive bays that just aren’t marked as anything special. Cases with power supply basements tend to hide at least 2 drives down there. Or there’s the classic drives in the front and you can fit a ton of 3.5" drives up front in an mATX or even ITX formfactor.

    If you’re planning on upgrading I’d highly suggest getting a case with at least 1 more free HDD bay. Replacing a drive in ZFS is a LOT quicker than resilvering a drive. I just did that the other day and I actually thought it was broken it went so quickly.






  • Do you already have a NAS? You could go back to your original setup, but with a more efficient CPU and run it all on one box.

    N100 devices are neat, but those CPUs are really slow. Running the rest of the computer, plus the inefficiency of the power brick does add up to the power usage/heat output. Consolidating into one efficiently tuned device can save a lot of power.

    Aliexpress has some funky boards which are laptop CPUs soldered to an mATX motherboard, if you can find a nicely sized case you could maintain that all in one formfactor, but with the efficiency of a laptop. I have no experience with them, but they look cool and should do what you need. They’re essentially your mini pc but as an ATX board so you have expandability.
