Gonna echo some of the other replies on what I've used at home that's helped me out.

1. Media - Used Windows Media Center on Windows XP/7 to start with > XBMC/Kodi > Plex - on several different machines

2. Networking - First wireless router was a Netgear N750, and it was great until the wife spilled some water on it > Netgear Nighthawk R7000 > Ubiquiti Edgerouter ER-X and UAP-AC-LR Access Point > still using the ER-X router but got a U6-Lite AP and then an Engenius controller and ECS-357 AP > ER-X and Aruba AP315/325 converted to be IAP models.

Got a Meraki MS120-8LP switch for POE for my APs. Ended up getting a bunch of Cisco switches and routers of different models to use at home from my current job. Still haven't setup a working lab with those yet.

3. Compute - This has been the most recent developments due to getting disposal mini desktops from work. Currently have a 3 node Proxmox cluster with 2 Windows server 2022 eval vms. One is a domain controller and the other is going to be setup for MECM(new acronym for SCCM).

I reckon that's it for now.
