Hey everyone, it’s been a minute since I dug into node hardware (about 5 months since I was deep in the research), and I’m finally pulling the trigger to get my node live next weekend.
I really just need some technical savvy eyes on this to let me know if I'm missing anything or if I'll run into friciton or limitations!
My main goal is long-term sovereignty—I want to verify my own transactions without pinging third-party servers and have a setup that doesn't need an upgrade for at least 5 years. I’m leaning towards a StartOS (Start9) setup for the privacy focus.
Here’s the list I’ve put together. Does this look right for 2026? Anything I’m overpaying for or missing?
The Brain: Looking at either a refurbished Dell Optiplex 7050 Micro (i5/16GB) or a Beelink S12 Pro with the Intel N100. I like the Optiplex for the build quality, but the N100 seems like more bang for my buck. Anyone have a strong preference here? Not super experienced with computer technicals so wanting to make sure the Beelink S12 isn't going to cause any potential issues or limitations in the future.
Storage: Going with a 2TB NVMe SSD (probably the WD Black SN7100). From what I can see, the chain is pushing 750GB+ now, so a 1TB drive seems like a mistake if I want this to last. Is the SN7100 adequate given the hardware it will work with?
The "Vault": Planning on a Coldcard Q so it can be truly air-gapped and "hack-safe". I’m prioritizing a "BTC-only" firmware and a clean bridge to the node via Electrum.
Is there a specific "trap" I should watch out for with the N100 or the StartOS install on these mini PCs? I'm planning to wipe the drives and flash the BIOS immediately to clear any bloatware/management stuff.
Thanks for any hole-poking you can do before I hit "buy" on Amazon/eBay today.

That is more than enough, the most important thing you should care about is the SSD size and speed, but especially speed as Bitcoin Core (and its forks) do a lot of IO writes and reads so validation takes a loooooooooooooong time in slower disks.
Size only matters if you want to keep a full copy if the chain, which you really don’t need unless you are running an Electrum Server of Frigate for SPA scanning.

Yes, Is there a reason you are setting up a new computer instead of hosting your full node locally on your own laptop or desktop ? Are you under the impression you need dedicated hardware to run your own full node ?
>Going with a 2TB NVMe SSD (probably the WD Black SN7100).
Is there a reason you are choosing to run an archival full node ?
>Looking at either a refurbished Dell Optiplex 7050 Micro (i5/16GB)
Why are you using such a overpowered system ?
