I live in the Southern US and it's extremely humid and hot in the summers. Only certain systems are fine with being in the garage. For instance, a Supermicro chassis I put out there began rusting in a few spots after a few months, but my custom system that I built was perfectly fine. I suspect the metals Supermicro uses are treated in some way and then cut, but the edges aren't re-treated, allowing rust to form on all of the edges of the chassis. I never put spinners out there, only SSDs. My bulk storage lives inside my house. I have an HP Sandy Bridge Xeon box that lives out there and it's always super quiet, but I don't push it hard either. Raspberry pis are super okay with being outside. I'd say if you can make a small Pi cluster, it's a good fit. I use an open air rack next to my water heater. I don't do any woodworking or anything, so the dust isn't too bad.
