Oh boy, where do I even start. I guess we should first have a minute of silence for my wallet…
Fixing old computers
In high school, I agreed to take the decommisioned PCs home. They were in various states of not working, I diagnosed the problems, bought parts, upgraded and fixed them all. I now had a ton of relatively old but reliable computers. What’s the logical next step?
Home server room (homelab).
I live in a flat with a giant basement, so it’s full of these old PCs and servers. I needed a server rack, switches, cabling, the whole nine yards.
Photography
New lenses and filters constantly bought. Sometimes a new camera body. This is my most expensive hobby by far, but I take care of the lenses so they at least hold value, unlike the PCs :)
