Youtube literally flat banned any channel with CP in it. Regardless of what CP actually stood for, like say combat power in pokemon go… Lots of bigger YouTubers got hit with account closures for like a week before it got reversed.

As the computer nerd in my friends/family circle, Im constantly being gifted old PCs from people. Some I keep and repurpose into servers/other things and others I just recycle for them. I also am an avid PC gamer so when my rig gets retired I usually upgrade the other servers internals from parts I had left over. Don’t know if something else is viable for you to keep costs down, even if you can get the PC without a HDD but everything else.
