I'm planning to build a PC that will also serve as a media server for movies, music, and archived videos. Storage has become a major concern, and most of the internal drives I'm finding are 3.5-inch models. I'm not sure which cases support that size or whether 2.5-inch HDDs are still commonly available. Should I be looking for a case with dedicated 3.5-inch drive bays, and which drive type offers the best value for a media library?

For a media server, prioritize a functional case over a design-focused gaming case. Cases with minimal glass and better airflow often include more drive mounting space. Use a case filter for the number of internal 3.5-inch bays you want, since drive support varies quite a bit between models.
2.5-inch drives are still available, including both laptop-style HDDs and SATA SSDs, but they’re no longer the best choice for a large media library. Most 2.5-inch HDDs are aimed at laptops, while 2.5-inch SATA SSDs can be relatively expensive for their capacity.
A typical setup would be one or more 3.5-inch HDDs for media storage, plus an SSD for the operating system and applications. M.2 NVMe is the modern choice for the OS, while 2.5-inch SATA SSDs are mainly useful if your case or motherboard setup makes them convenient.
You can also consider used or recertified enterprise 3.5-inch drives, which are often available in larger capacities and can work well for a Plex-style library or backups. Just check the drive’s health, power-on hours, return policy, and noise level before relying on it.
For bulk storage, 3.5-inch hard drives are usually the better option because they offer much more capacity per dollar than 2.5-inch drives. They’re still the normal size for desktop HDDs, and plenty of PC cases have mounts for one or two. If you need several drives, look specifically for cases with four or more internal 3.5-inch bays.
That sounds like what I need. I mainly want reliable space for movies, music, and videos, so capacity matters more to me than having a flashy case.
