Tower PCs are computers in which the components are stacked vertically within the computer’s chassis. They usually stand upright on or under a desk (hence the name) and come in a variety of sizes and configurations. Out of all the different types of PC, tower PCs are the most flexible and upgradeable because there’s more room in the computer’s chassis to install or upgrade components such as storage devices or extra cards for connectivity. The downside is they take up more room than other, more compact PCs such as micro PCs and all-in-ones. They can also be noisier and consume more power than other types of computer.
When shopping for a tower PC, you should consider how you plan to use the PC and what type of applications you need to run. Refer to our PC buying guide for a rundown of the most important specs to be aware of. If you’ve decided you specifically want a tower PC, there are several variations to pick between. Tower PCs are generally grouped into three main categories based on the size of the case required to house the PC’s motherboard.
Full tower PCs are the largest and contain the most expansion bays, slots and ports. If you have the space to house one and want to invest in a tower PC that’s future proof and can be upgraded as your needs evolve, an ATX tower PC could be the right choice. Full tower units typically measure 24” or more in height and contain up to 10 internal bays and a similar number of PCI slots giving you plenty of room for expansion and connectivity.
Mid tower PCs are a touch shorter (usually in the 18 - 24” height range) and represent a good balance between size and upgrade capability which is why they are the most common type of tower PC available. Mid tower PCs come with up to 4 internal drive bays and 5-7 PCI slots.
Mini tower PCs are the most compact type of tower PC, measuring between 12 and 18 inches vertically. The smaller chassis means they’re more flexible when it comes to placement but expandability is also limited due to the lack of space in the PC chassis. You might find a mini tower PC with 1 or 2 internal bays and up to 3 PCI slots.
