I went down the route of a Raspberry Pi 5 and Installing Dietpi as the OS. Dietpi has loads of recipes in its main app that makes it easy to get going, plus if you install docker you have a huge range of stuff to try.

There is a learning curve but it’s not too steep and I’ve enjoyed it.

I’ve been going down the slef hosting rabbit hole recently.

First, Home Assistant is worth doing - you’ve not got a smart home yet but this is the easy way to get one going. So worth it. You can buy a few cheap WiFi plugs, and plug in devices like lights or stuff you don’t want on stand by and you have the start of a smart home. A smart thermostat and smart radiator valves are surprisingly easy to set up if you want to save some money and keep your home efficient - a bit more of an investment but worth it if you find you like the ease and power of WiFi plugs.

I also recommend Pihole - it’s an ad blocker for your entire network. You can run it on Docker on x86 machines - you just point your router to use it as the DNS and it then filters all requests for you. It’s really improved my experience on all my devices.

Next, Paperless NGX - scan your documents and paperless NGX will OCR read them to make them searchable and keep them in a database for you. You can use it to go paperless. Just make sure to sort our a backup.

Joplin is quite a good note taking app which you can self host to sync your devices and keep your data secure.

Syncthing is fantastic for syncing files between devices. I sync my main PC and living room theatre PC, plus in my case my Raspberry Pi as an always on broker and local backup.

Some good advice already in this thread.

Also worth considering QEMU as an alternative to VirtualBox. The Virt-manager tool is decent way of managing machines, and it’s relatively straight forward to create a base machine if you’re duplicating it. Virtualbox is perhaps initially more user friendly for absolute beginners, but once you have any familiarity with virtualization I’d suggest QEMU offers much more.

Also I find integration between the guest and the host linux system is generally more straight forward. Most linux systems already ship with samba and other relevant tools QEMU uses to interact between host and guest. There isn’t a need to faff around with the guest-additions stuff. Plus KVM virtual machines can run with near native performance.

I have one of these, it’s a decent mini PC. It’s decently powerful - I used to play some steam games on it; a bit equivalent to steam deck or a bit more powerful. I used it for streaming on my home TV. I upgraded to a even better one as I liked it so much - and wanted to do more gaming.

It’s a full PC basically. Whether it suits your purposes really depends on what you want to host? It could be overpowered and a bit redundant for a lot of self hosting uses.

I have a Raspberry Pi 5 which is cheaper than this, and am hosting docker with Home Assistant, Sync thing, and fresh RSS running on it at the moment with plenty of spare memory and cpu resource.

This mini PC is considerably more powerful and will have a higher power use at idle. You may struggle to use it at capacity so may be a bit wasteful?

And even the rasp pi 5 is over powered and expensive for a lit of common home server users.

So whether this PC is a good price and choice really depends on what you want to do with it. It’s at the end of the spectrum of being able to comfortably play 4k video. So it’d likely be a decent Jellyfin streaming host if that’s what you want?
