What do you want to self host? To learn or experiment buy a cheap old x86 box. I get mine at goodwill auction. Otherwise desktop is good if you want something that needs more compute and that you’d spin up as needed vs always on.
I would learn about mtbf if I were you. Everything has a failure point (generally buried deep in product info), and when you start keeping it on 24/7, the hours will burn. Those fans on your GPU will give it up way before they normally would.
Finding a used server is not a good idea either. You aren’t in a data center and servers are super loud. Also, they chew up electricity like a hungry dog and his dinner.
As others have said, find a used desktop somewhere and a cheap KVM switch so you can use the same peripherals for both. It doesn’t need to be beefy by any measure (maybe drive space), just affordable.
Whatever works for you. Just do it. It is convenient as f when you are just starting. You can always improve incrementally later on when (if) you encounter a problem.
Too much noise/power costs to run a small thing - get a pi and run it there. Too much impct on your desktop performance - okay, buy a dedicated monster. Want to deep dive into isolating things (and VMs are too much of a hassle) - get multiple devices.
No need to spend money (maybe sponsoring more e-waste) and time until it’s justified for your usecases.
I used to have a separate machine for server stuff but it just cost more in electricity since I would leave them both on 24x7 anyway.
I’ve got 64G of ram and I often use up to 48 of it with various VMs. I wouldn’t get any power savings with a separate server since I have a cron job to transcode everything that plex recorded off of TV during the day to av1 for disk space savings (usually turns 3GB of mpeg2 into 700MB of av1), so I would need a server with a moderately powerful cpu anyway for that.
I have a ryzen 3700X. got it since it was the highest performance that was still 65w tdp at the time, didn’t want to spend a ton on electricity and extra air conditioning since I would be leaving it running 24x7.
The only time I notice a performance impact during gaming is if my windows 11 vm is running, I don’t really need that one running 24x7 so I shut that one down if it happens to be running at the time.
My first homelab was a synology NAS, and my gaming PC with a DIY linux hypervisor as the main OS, a linux VM for hosting servers, and a Windows/Mac/Linux VM trio (each with GPU passthrough) that I would switch between for my workstation. I lost performance for sure, but it taught me a lot without the need to purchase more hardware.
If you consider it temporary, it’s not a bad way to learn.
By hosting services on your desktop, you are increasing your threat surface. Every additional software that you run increases your potential to catch malware. It also requires powering a beefy machine 24/7 to keep the service up, when in reality anything that isn’t a media server can run on 3rd gen Intel CPUs that have relatively low TDP.
I did the other way round. An old nuc from 2013 turned into a gui-less debian selfhosted server (yunohost) for 2.5 years, until my old laptop (2008) died. Then I installed xfce on top, plugged a wireless keyboard/touchpad combo + hdmi to my TV, and use it as a desktop mainly for web browsing, open office and some gimp processing. But just once a week or so.

I do and it’s fine.

I use a “regular” desktop as my server. It uses much less power than most servers and still has plenty of horsepower for what I do.
Remote management and (cheap) ECC ram are the biggest reason to get a server. But those usually aren’t issues for most work loads, especially at home.
Shit I used to run my stuff off of a laptop with maxed out ram, and some people just have a raspberry pi and call it a day.

Convenience is the main issue. AFAIK, as long as you secure your device, it’ll do the job

And if you’re allergic to buying used, there’s always the mini computers.

If you are going to use your desktop, I would suggest putting all of the self-hosted services into a VM.
This means if you decide you do want to move it over to dedicated hardware later on, you just migrate the VM to the new host.
This is how I started out before I had a dedicated server box (refurb office PC repurposed to a hypervisor).
Then host whatever/however you want to on the VM.
