Many of the computer sellers like Gateway, Dell, HP and so on use parts that are tailored to a specific build and not standard. Additionally, technology changes.
I was able to reuse a PSU and ATX case from a previous build but the new motherboard had connectors pointing forward rather than up and it made connections difficult but not impossible. It is important to identify the components you want to use, the necessary connections and the dimensions of each part and the space in the case.
I have a multi purpose computer and prefer to put multiple drives, my motherboard, PSU, memory, CPU and GPU in a larger case, but others use their home theater computer solely for media and use a tiny case. There are many ways to build a computer.
You may indeed need a new case and a new PSU.
Renethx, a regular poster in AVS forum used to publish suggested components which would work together. Tomshardware.com posts builds, however usually not specifically HTPC builds. If you are not a gamer you can save money and have less heat and noise by selecting parts only capable of doing what you want to do.
In two years you will have aging technology. In five years you will have an antique.
