I'm pretty much new to all things homelab as I've only started looking into it because of my job. I'm relatively new to my position (first job I got after getting my degree), so I wanted to learn more about virtualization and other related tools that could help me.
I want to practice using VMs and such. VMware vCenter, ESXi, PowershellCLI, Microsoft Windows Servers, RHEL, and others. And while my work does provide me a remote production environment for these, it's not always available to me. A lot of other people work on them and I can't really just go in and start messing around.
So I've been looking into getting a homelab setup for myself. I'm just not really sure what I should be going for, though. Do I get a Dell Poweredge Rxx0? I do have a PC of my own that I've been using with Hyper-V and VMware Workstation to create VMs of what I mentioned, but I dunno if I should just get a dedicated server or not? Should I just upgrade my RAM and add in some SSDs on my PC and would that work fine for me?
I would suggest you either use the RPIs you already have or try to get an old laptop somewhere that you can use as a beginner server.
You desktop PC is likely a gaming PC and those aren't optimized for server use. It can work, but it isn't really a good way to start out.
I do have an old laptop. Can you tell me why it's better to run a server on an old laptop than a gaming pc, though?
Much lower power-consumption and built in UPS. Usually also more quiet and since it has a built in screen and keyboard, it is easier to recover from user errors compared to RPIs for example. Disadvantages are mainly the limited storage expansion options, but that is unlikely to be a problem for a beginner.
If you can get a laptop with a few USB ports that can go a long way to helping with storage expansion. Try to avoid USB drives and SD cards, but attaching proper SSDs and HDDs with a USB caddy is a great option. Just don't accidentally pass the boot drive USB controller to a vm like I did once.
