I'm looking for a new PC case, but I don't know what to buy: ...... Don't worry, you don't have to worry. We found five great models on sale for Prime Day that are spacious, good-looking, feature-rich, and affordable.

First up are the Corsair 4000D Airflow and 5000D Airflow. They are almost identical, except that the latter is considerably larger than the former. Both models are rather bare-bones, with only two 120mm fans each, but their simple design makes them very easy to handle.

The 4000D Airflow is a great choice for PC gamers who don't want a huge case taking up most of their desk, but I give the edge to the 5000D Airflow. The interior has room for large graphics cards and radiators, and cable routing is easy.

Neither is particularly stylish, but Fractal Design and Lian Lia have it covered.

My favorite of the five cases I chose is the Fractal Design North. I bought the white version for my partner's gaming PC and the North XL (big) for myself. The standard North can be a bit fiddly, especially when mounting a radiator on top, but you can also remove the two pre-installed 140mm fans and mount a cooler there.

I like the elegance of the design. Even the power button feels high quality, made of brushed metal and with a switch that operates with a dampened feel. Admittedly, the overall construction is a bit chunky due to the steel casing, which is designed to keep weight as low as possible, but once it's on, it's not particularly noticeable.

On the other hand, if you buy the Lian Li O11 Dynamic EVO RGB, you will not fail to notice its case. It looks amazing and begs to be filled with RGB fans. However, it is very large for a mid-tower case, and its weight makes it difficult to move.

But if you want something in between Fractal Design and Lian Li in terms of looks and features, the Be Quiet! The Shadow Base 800 FX has four 140 mm PWM fans, ARGB lighting, and a traditional and modern The Shadow Base 800 FX features four 140 mm PWM fans, ARGB lighting, and a design that is a perfect blend of traditional and modern.

It is also very quiet in use and comes with a sheet of sound deadening foam under the rear panel to absorb vibrations.

All five PC cases are excellent choices, and no matter which one you choose, you won't want more space or better airflow.
