if divided by size, HTPC MINI medium tower, high school, full tower
The first two do not have standard sizes
The medium tower is average. It has 4 optical drives, 2 floppy drives and 5 hard drives. The relatively new structure is 3 drivesoptical and 7 hard drives.
High-end towers generally have power supplies placed lower than medium towers, but the number of cabs remains the same.
Full towers have lower power supplies than mid-towers. an additional optical drive slot
Nowadays, many chassis support hard drive cages that can install the hard drive into the optical drive slot. The floppy drive slot is gradually disappearing.
