Computer enclosure incorporating fixing structures for fans

A computer enclosure assembly comprising:

• an enclosure including:
• a panel defining a lengthwise direction thereof and an array of apertures therein;
• two sets of first retention devices formed on an interior face of the panel and defining two different dimensions along said lengthwise direction;
• a fan positionably retained by one corresponding set of the first retention device in said lengthwise direction;
• opposite first and second side plates located inside the panel, each of said first and second side plates defining a second retention device restricting said fan from moving along a transverse direction perpendicular to said lengthwise direction and along a front-to-back direction perpendicular to both said lengthwise direction and said transverse direction;
• wherein
• the second retention device of at least one of said first and second side plates defines two different retention positions, and said fan is secured to one of said two retention positions, whereby
• another fan is adapted to be secured to the enclosure by means of the other set of the first retention device on the panel and the other position of the at least one of said first and second side plates, so that the enclosure is allowed to receive two different fans mutually exclusively.

A computer enclosure comprising

• a panel defining a plurality of openings extending therethough in a front-to-back direction;
• upper and lower bracket units formed behind the panel along thereof a lengthwise direction perpendicular to said front-to-back direction,
• said upper bracket unit including two opposite side walls, and a bottom plate integrally extending from one of said side walls with thereof a transverse bar extending along a transverse direction perpendicular to both said front-to-back direction and said lengthwise direction;
• and
• said lower bracket unit including a first side plate split and integrally extending downwardly from the bottom plate, and a second side plate opposite to the first side plate;
• wherein
• said upper bracket unit is larger than the lower bracket unit along said transverse direction, and said first side plate, which is integrally formed with the bottom plate and the corresponding one of the side walls, is smaller than the said corresponding one of the side walls in said front-to-back direction.
