Top PC Case with Lots of Hard Drive Bays for NAS & Server in 2024

Most of the mid-tower to full-tower ATX computer cases in the market offer a sufficient number of bays for normal storage needs. However, if you want to build a home server, NAS server, backup server, or media server then you need a case that can accommodate a lot of hard drives, preferably 10 drives or more. Also, if you are a professional who is into video editing, and sound editing and works with a huge amount of raw data then having a case with lots of hard drive bays can come in very handy as you can easily expand the storage capacity of your PC or workstation by adding more hard drives. So, if you are looking for such cases that come with 8 to 10+ HDD cages or bays then here I am going to list some of the best ones out there in the market right now. These are non-server chassis and are standard ATX PC cases that also have good airflow so that your hard drives / SSDs and other components remain cool during continuous operation under heavy loads. Also, some of these PC cases do come with hot-swappable drive bays or cages for easy access to the drives.
