It's large, blocky, and designed to stand up-right. The Small Mini-Tower, or just Tower, definition will cover everything from the large Optiplex and Dimensions to the very large XPS gaming systems. *Desktop (DT) - The Desktop form-factor, sometimes referred to as a Small or Slim Desktop, is Dell's middle-of-the road size. It's small enough to fit on top of your desk, but with more space to expand than the Small Form-Factor system. *Small Form-Factor (SFF) - Small Form-Factor systems are typically Dell's smallest consumer PC. These computers use a laptop sized optical drive but, unlike the Ultra-Small Form-Factor, do include an internal power supply. *Ultra-Small Form-Factor (USFF) - Dell's Ultra-Small Form-Factor systems are as small as they get. These computers, like the Small Form-Factor, use a laptop sized optical drive, but are so small they require an external power supply.
