Big Tower is the designation for the largest commonly available type of computer case. Its main characteristic is a spacious interior designed to accommodate the most powerful and largest hardware components. Due to its size, it allows for the installation of large motherboard formats, such as E-ATX or “Extended ATX,” which offer more slots for RAM or expansion cards. The large internal volume also provides sufficient space for advanced cooling systems, such as bulky CPU air coolers or custom water cooling loops. It allows for the installation of multiple graphics cards and a large number of hard drives or SSDs. Working with components inside the case and cable management is generally more convenient in such a spacious layout. This type of case is intended for building computer systems where emphasis is placed on maximum expandability and cooling performance, typically for gaming enthusiasts or professional workstations.
