So if I decide to go through with building a PC this year, where would be a good place to start for someone with no building experience?
e.g. why would I buy X case over Y case, A fan over B fan, etc.
PC Part Picker is a good place to start as they have a part list organiser. It shows you all the basic components needed for a computer.
Moving from there, you can look up what each part does and try to get a feel for what you are looking to get for your needs.
I'm a bit busy at the moment so I can't type anything too much, but I can help run you through the stuff when I have time tomorrow morning. If you have a Google hangouts account I might be able to chat with you live if you really have a hard time with something.
Since we are at PC Part Picker, I recommend you take a look at as many of their video guides as possible (make sure it's the official video guides. Many of the build guides are by the community who build them for fun. They are nice, not not necessarily beginner friendly and sometimes not even practical). Some guides from other sources are a bit coloured (*cough* Tek Syndicate's old PCMR elitist guides) or are not as clean. For people who are more experienced, it may not be an issue, but if it is your first time, it may be confusing. The reason I recommend PC Part Picker is because their videos are great and simple, with no jokes or sarcasm that are not always obvious to people who are unfamiliar with the terms. Anyways, watch the videos on PCPP so you can at least start familiarising yourself with the terms that people use and start researching from there. Understanding the demographics of every component is quite overwhelming at first. That's normal so take your time. ^_^
After you start to be able to piece things together in your head, you can start looking at reviews of individual components (know how every company's nomenclature works, understanding features, get a basic idea of the pricing/performance hierarchy,
know what's pure marketing bs and what's actual useful features that is worth considering, etc.). Hopefully by then you can start to work on a basic idea of a practical PC that suits your needs.
People can start to help you and improve on your parts list as communications is smoother.

Random video I grabbed from PCPP YouTube channel. Quickly scribbled through it. Nothing I see wrong on first glance.
If someone has a better suggestion, please share it as I actually only briefly scrubbed through this video:

Edit: previous video used a fairly unusual case. Switched it to a more standard looking one.
