I assembled everything with my own hands from old fans and power supplies several times, but in the end it is difficult to beat this figure with 4 sets of grills. , speed switch and rubber feet, it's just not worth making them yourself when you can get a walkthrough at this price point. Especially when older power supplies can be less efficient. The legs are soft and quiet at low speed. Ideal for cooling some external hard drives in summer. Just be aware that only about 30 inches is possible between the fans and between the fans and the connector, they should be clearer in that regard.
