Finding the right computer case size can be difficult depending on your needs. Large, mid-, and full-tower cases offer a lot of space at the expense of room on the desk or floor. Compact and mini-cases are great for portability but can be challenging to fit large graphic cards and CPUs. Sitting in the middle are cube cases that are smaller than full-size options but maximize space inside. Much like regular cases, cube cases are designed for many uses. A good general case is perfect for an everyday computer. Gamers wanting a small rig, on the other hand, should check out models with more ventilation, side access panels, and optional LED lights.
