Not suitable for modern Motherboards, Coolers or GPUs
The N400 offers a decent number of drive bays and airflow options, but several design choices made the building experience more frustrating than it needed to be. * The PCIe slot covers are flimsy and do not provide much support for add-in cards, resulting in poor alignment with the motherboard slots. * Only two of the 3.5” drive bays include tool-free mounts, while the rest require screws. * The 2.5” SSD mounting system is also of low quality and difficult to manage, making cable routing more challenging than it should be. * There is very little space above the motherboard, which makes it difficult to connect cables, especially when using a tower cooler. While the case technically supports two fans in this area, there is realistically no room for them if a larger air cooler is installed. The same goes for the two fans which can be installed behind the drive bay, as they share the same space as the 2.5" mounting adapter. * The case is not designed with right-angle motherboard connectors in mind, meaning compatibility may vary when using SATA, USB, 24-pin power connectors etc. * The included fans are functional but do not compare well with modern, quieter alternatives. * The dust filters are not easy to remove for cleaning. * The case does not come with common motherboard standoffs pre-installed (e.g those shared by both ATX and mATX), which adds an unnecessary step to the building process. * There is no AIO support here. You might get one mounted on the rear 120mm fan, but that isn't going to be enough for modern hardware. If a budget case with storage capacity is the main priority, it can be made to work, especially as you'll be saving a lot of money vs alternative high-drive capacity cases.
