My recommendation: Get a Raspberry Pi 4 and an external SSD. If you want to spend less for the external storage, get a HDD instead. For the software get MyNode for free, or pay the $99 to unlock certain features (not required.)
This is another layer of complexity on your path towards taking complete ownership and responsibility of your current and future wealth. Running a Bitcoin node is not easy exactly, especially if you are not comfortable with technology. But it is also not hard as long as you follow some simple steps.
It takes a little work, it takes a little money, and it is very well worth the effort and resources. Running a full node gives you the ability to confirm your Bitcoin transactions and gives you the ability to verify what you expect to be true with minimal trust.
As noted above, I recommend a Raspberry Pi 4 for this setup. If you are unfamiliar with a Raspberry Pi, these are very basic computers that are very cheap and run Linux. There are different implementations of Bitcoin stacks out there for the Raspberry Pi, so there are plenty of options on how to get this done. You will also need an external storage solution, so pick up either an SSD or an HDD depending on how much you want to invest in your setup. An SSD is going to be faster, but it’s not needed. Last but not least, decide on the direction for the way to want to run a Bitcoin node.
You can run just a full node and electrum server for the sake of simplicity and for the sake of not having to trust a pre-built stack. I recommend following ArmanTheParman’s directions for that. This is going to be more complicated than running something like MyNode.
Here are some other options for Bitcoin node software:
