A step down in size from our full tower case range and what we would classify as a mid tower case. Mid-tower cases are the most widely used computer cases. Mid Tower cases are about 18 to 24 (45 to 60 cm) inches high and they usually contain 2 to 4 internal drive bays and a similar number of external bays (for CD/DVD readers and similar). There is also ample space in some of our mid tower cases to accommodate a full size graphics card and Multi CPU All-In-One Hydro Cooler.
