Electronic device enclosure

An electronic device enclosure comprising:

• a chassis defining a sliding slot and comprising a bottom wall, a sidewall connected to the bottom wall, and a limiting protrusion protruding from the sidewall;
• a bracket received in the chassis;
• and
• a mounting assembly comprising:
• a resisting member secured to the sidewall and comprising an elastic deformable resisting portion;
• a rotating member rotatably attached to the sidewall and comprising a first blocking portion and a blocking piece;
• and
• an operating member rotatably attached to the bracket and comprising an installation portion and a second blocking portion extending from the installation portion;
• wherein the limiting protrusion is received in the sliding slot and located between the first blocking portion and the second blocking portion, the operating member is rotatable away from the bottom wall to bias the installation portion to rotate the rotating member through the blocking piece;
• the rotating member is rotatable away from the bottom wall to bias the blocking piece to elastically deform the elastic deformable resisting portion;
• and the first blocking portion is rotatable to bias the limiting protrusion to slide in the receiving slot and disengage from between the first blocking portion and the second blocking portion.
