CPU Bays
In the case that holds your system together, make sure you have enough room to hold all the equipment. Some people like to settle for smaller cases because it might be more compact or portable, but there has to be enough room to hold at least one DVD-ROM drive. Some special sound cards may require a 5.25” bay to hold some sound controls, switches and ports. Liquid cooling systems require a reservoir to hold all the liquid. The best place to store a reservoir is in one of the bays. Floppy drives and zip disks are rarely used these days, so no worries about them. Keep the 3.5” bays free for hard disk drives. Even if there’s enough room for them now, you may want to keep them free for the future when you decide to upgrade.
