Case
The case is the component that will house every other part. Practically speaking, all cases are the same, except for the size and airflow (different cases will have different fan placement, for example). Aesthetically speaking, all cases have differences. Some are more subtle. Some have rainbow lights strewn across them.
When picking a case, first determine what size you want, then pick one that looks appealing to you. Below, you can pick from FATX, ATX, mATX, and ITX. FATX is the largest size, and can fit nearly any hardware you put into it. These towers are typically about 2.5ft to 3ft tall. ATX are the second largest, and can stand 1.5ft to 2.5ft tall. These will house most components comfortably, and are usually a great pick for a full-featured and expandable gaming PC. mATX is a bit smaller and won't be housing ATX motherboards, but at about 1ft to 1.5ft tall, they're great for keeping a lower profile. Most non-gaming systems from big-name brands are mATX. ITX is the smallest. These are usually about the size of a blu-ray player or video game console, like the PS5. These may require unique cooling and will limit your storage options, but even ITX systems can be extremely powerful.
