  • Edit 2: Eheran pointed out I screwed up the math. Correct total energy output is 13μWh. A very, very, very small amount of energy.

    (2x1015 W) * (25s/1x1018) * (1 h/ 3600 s) = 13μWh


    Previous bad math:

    spoiler

    The key thing here is the burst lasted for “25 quintillionths of a second long”. Meaning it had a total output energy of 180 W/h, or how much energy a standard US space heater (1.5KW) outputs if it was on for 7.2 minutes.

    That is a pretty impressive amount of power coming in instantly to a small spot. Would leave basically zero time for it to dissipate into surrounding materials.

    Edit: Fixed the math. (I hope) (2x1015 W) * (25/1x1018 s) * (3600 s / 1 h) = 180W/h

    A note on the fans specifically, you can buy quiet fans. In general, the larger the fan, the lower the speed you can run it and the quieter it is. You can also setup fan curves so they are only doing anything of note when the computer is pumping out heat (given your statements, that would be basically never).

    The electricity usage is a pretty notable thing. Though, if you take the graphics card out of a desktop (use integrated graphics, a dedicated graphics card in a server is just wasted electricity) and set the OS to power saver (this mostly means it won’t boost the CPU to higher clocks), it really won’t use much power. Compared to buying dedicated NAS hardware, you may never recoup the energy costs between the hardware you have and the lower-power hardware you need to buy.

    If you don’t already own one, a Kill-A-Watt is a great tool to have. Tells you how much energy a device is using. Biggest thing I found was my TV had a vampire draw of 15W. Literally draws 15W while off. This got the TV put on a power strip I turn off when I’m not using it.

    Now, with all that said, sometimes you just want what you want. And there is nothing wrong with that. My goal here is to make sure you don’t feel you have to pick one option over the other.




  • What are you intending to run on this server?

    • If it is just PiHole, you can basically get the weakest computer you can find.

    • If you want lots of storage space, you will need to make sure you have a case and motherboard that will accommodate the drives.

    • If you are running encryption on those drives as well, you will need a CPU more powerful than what comes in a Pi, but nothing crazy.

    • If you are running lots and lots of VMs, you will want lots of RAM. A linux VM will use maybe a few GB each depending on what software each is running internally, a windows vm will use a bit more.

    • If you are doing AI workloads, you will need a graphics card.

    Those are both solid pieces of hardware. However, I would suggest getting a Ryzen 5600 for a notable per-core CPU buff over the 3600x, which should help quite a bit with games like Civ’s AI turn time. And since that CPU, Motherboard socket isn’t latest-gen either, you can buy used for cheap still.

    Ryzen 3600x vs Ryzen 5600.

    On a slightly different note: The 7k series Ryzen CPUs get you on the latest slot, AM5. This will get you future upgradability if you want it, but it will also come with higher costs as AM5 is the newest socket, so people aren’t unloading them onto the used market in quantity. Such cost considerations are best determined by you. Both are a solid choice though.


    For the GPU, I think the Radeon 6600 is a good choice. Radeon stuff works better in linux and that particular one is plenty strong for what you listed.


    I highly, highly recommend PassMark’s benchmarks for comparing hardware. They are the first place I look to get relative numbers. And from there I determine what I need/want.
