What are the Different PC Cases Sizes?
PC cases come in many shapes and sizes but can generally be grouped into three main categories: Small Form Factor, Mid Tower, and Full Tower.
- Small Form Factor cases include those that utilise Mini-ITX and Micro-ATX motherboards. They are ideal for the PC enthusiast who wants a powerful gaming PC but has limited space or must travel a lot. An SFF PC case can come in a range of configurations, from console-like cubes to small footprint towers. Many of these cases require specialised components, such as SFX power supplies, low profile coolers, and Mini-ITX motherboards. Although small, an SFF case offers an outstanding cooling to performance ratio, with many featuring full mesh panels, alongside support for radiators. Perfect for keeping powerful components cool.
- Mid Tower PC cases are what most people consider to be the standard case size. Within the internal structure, there is normally enough space for an ATX motherboard, with some even able to support E-ATX boards. What’s more, you can install a full range of powerful components, such as AiO CPU coolers, ATX power supplies, and full-sized graphics cards. Mid Tower cases offer an exceptional balance between cooling and performance, thanks to excellent airflow designs. Many feature multiple locations for both fans and radiators to be installed.
- Full Tower cases offer the ultimate in space for components, with the ability to easily install E-ATX motherboards, NVIDIA RTX 4090 graphics cards, and other large hardware. What’s more, their spacious chambers are ideal for custom water-cooling solutions, thanks to their multiple mounting positions for radiators, numerous fans, a waters pump, and reservoir. This makes them an ideal choice for overclocking. You can find a diverse range of shapes and styles of full tower PC cases, from the traditional tower to showpiece wall mountable designs.
