I did a stint of YouTube gaming and coding tutorials at one point, I've sometimes considered getting back into it. I doubt I would because I'm a little too privacy conscious these days but it's a consideration.

Plus running Minecraft and other older games at 1k fps sounds hilarious. I think I'm realising I can find use cases for the upgrades

In terms of learning tech, I'm not looking to learn in the traditional "home lab" sense. I work in cyber, and the vms I'd be running are likely different from a regular home lab. I'd be learning how to make a windows domain and how to attack/defend/configure. Realising now I should have said that in the post.

I do like the idea of having a server rack but I don't have any storage space for that so it's a future idea at the moment. Hence upgrading the tower to effectively be a server but also gaming.

Might be a dumb question but how would these go for storage? Can you plug a lot of drives into them?

I'm a nerd with a thing for punishing myself so setting up a small fake corporate environment that I can hack or configure would be fun. There's a tool called velociraptor that you can use to hunt over multiple devices which I want to learn.

Also just learning how to configure a domain, group policy, etc. I'd do like an 8 computer network if I had a machine that could run it. Setting up something like network segmentation, then "hacking" in and configuring attacker infrastructure sounds fun if not, again, totally overkill for what I want to do. I'd be phishing myself at the end of the day but it'd be fun to try.
