"Recommended System Requirements" for buying a used PC for selfhosting (lemmy.blahaj.zone)

I'm ready to graduate from my Raspberry Pi era of selfhosting and buy hardware specifically for use as a server.

I've been recommended in the past to look for used Lenovo Thinkstations and/or Dell Optiplex, but it has been so many years since I've shopped for a computer, I don't know what kind of specs to look for. What are the types of specs I should look for to get the best value for money?

I'm hoping to spend around $300-400, get something that can be upgraded in the future to last 10+ years, and do the following things:

YUNoHost / reverse proxy
Nextcloud with a custom domain for email addresses, cloud drive, photos
Music Streaming with something like Navidrome
Serve static websites
pi-Hole
Maybe pi-VPN

And someday maybe:

Host game servers like minecraft
Jellyfin for videos
Kodi and output to TV?

So far based on my selfhosted journey, I expect to want the following:

Room for 3+ Hard Drives
External UPS (probably will go with the cheap APC at Microcenter that's always on sale).
Solid Power Supply / Cooling
probably 1000 gigabit Networking (?)

The types of questions I have for Thinkstations / Optiplex:

How is the Power Supply / Cooling?
Processor? Do I need i5? i7? Generations? AMD? Clock Speed? I'm completely lost here.
How much RAM do I need?
Do I need a discrete graphics card? Can Thinkstations / Optiplex have a graphics card added to them later?
Anything else I'm missing?

Thanks!

transitioning away from raid but I do love zfs for flexibility. A lot of the data I have is important for someone or somebody, so zfs and a decent backup solution is in use just to make sure. I went bananas and picked up a used Supermicro 4-node server that takes dual E5 Zeons (V1 or V2) with 2xE5-2620s and 49 gig ram in each node for £80 (I'm in the UK). Plenty of power and next is to upgrade the cpus to slightly better cpus to reduce power as it currently uses 2 nodes and I am pulling around 300 watts most of the time. Backup solution is an old Ryzen 3200G with 32 gig ram that runs truenas and has 5x3tb spinny drives in it
