The first major problem in older style hardware is thermal cycling. Stuff heats up and cools on a regular basis, this causes fractures to develop in PCB tracks and solder pads. It's a bigger problem with fully enclosed type cases, but also some larger units can depend on small fans that can fail or become blocked with dust and debris.
The second major problem occurs with devices that have a built in PSU, is that the PSU capacitors fail, either they swell and burst causing the dielectric to dry out, or they grow crystals internally and short out across the dielectric. Most Capacitors are only rated at a fixed lifetime, whether they are in full use or sitting idle.
