Tower cases come in mini-tower, mid-tower, and big-tower/full-tower sizes. Full tower cases are typically 30 inches or more in height and intended to stand on the floor. They have anywhere from six to ten externally accessible drive bays, with more bays only internally accessible. The ratio of external to internal bays is shifting, however, as computing technology moves from floppy disks and CD-ROMs to large capacity hard drives, USB flash drives, and network-based solutions. Midtower cases are smaller, about 24" high with two to four external bays. A minitower case will typically have only one or two external bays and stand from 12" to 18" tall.作者: kim.lee 时间: 2009-4-26 15:19
