  • Basically, amps tell you how fast electricity is moving. If you have a certain amount of amps running through your body, it will kill you (I think technically no matter the voltage?).

    Why doesn’t every battery kill you? Electricity at low voltages doesn’t have enough “strength” to push through your body, as your (electrical) ressistance is very high. The higher the voltage, the higher ressistance it can overcome.

    So if you touch say 12 V, only very very few microamps will flow through your body, which doesn’t matter.
    When you touch 230 V, now the electricity is strong enough to push somewhere between 10 - 100 mA through your body, which will kill you.
    (No guarantees that the amperage numbers here are correct, but the scale should roughly work out I hope).

    It all boils down to $U = R \cdot I$ (Voltage = Ressistance * Current).

    If you want to learn more about the subject, ElectroBoom has some great videos.








  • I’ve been running an HP ProDesk 600 G4 mini (i5-8500T, 32 GB RAM) for a few years now and am very happy. I bought it with 8 or 16 GB RAM and a 256 GB M.2 for 140 €. It can fit one 2.5" SATA drive and two M.2 2280 drives. I have it running 24/7/365 with 2x2 TB M.2 SSDs and a 256 GB boot SSD and it usually uses around 7 Watts.

    If you want to go the HP route, ProDesk 600 and EliteDesk 800 have two M.2 slots, while the ProDesk 400 only has one.

    Alternatively, Lenovo and Dell also have similar formfactor PCs, but I don’t remember their names.

    Performance wise, the 8th gen i5 is more than fine for TrueNAS and 10-15 docker containers.
