## Background
TECHNICAL FIELD
Embodiments of the present invention relate to the field of electronic device enclosures. More specifically, embodiments of the present invention relate to an electronic device enclosure with sliding and pivoting doors.
BACKGROUND ART
Personal computer systems provide many different types of uses for computer users. For example, personal computer systems may be used for Internet/email access, personal financing, personal businesses, gaming, and many other uses. While many uses require minimal computing resources, avid computer gamers typically use the most modern and cutting edge technology available. These users typically use high-end gaming systems to maximize the user experience of the game they are playing.
Often, avid computer gamers transport their personal computer system in order to access off-site local area network (LAN) parties. In moving their computers, the protection of accessible electronic componentry, such as disk drives, is a considerable concern. Currently, computer housing manufacturers provide protection to the accessible electronic componentry by providing a door to cover the componentry. Current doors of computer system housings suffer from aesthetic and function drawbacks.
There are many different types of computer system housings that have doors for covering disk drives. One type of door is a full-width pivoting door that is the entire width of the computer system housing. Typically, these doors are very wide, and are inevitably in the user's way, as they effectively double to width of the housing. Another type of door slides down the front of the housing to reveal the disk drive, but covers up the bottom of the front of the housing, hiding decorative features common in gaming personal computers. The slide down door also often interferes with airflow of vents on the front of the housing. Moreover, typical computer system housing having doors lack the pleasing aesthetic appearance the avid garners often desire.
Moreover, gaming computer system housings often include decorative features. These features are often incorporate into the venting of the housing, so as to provide adequate airflow to the internal components of the computer system. Airflow is essential to the performance of a personal computer system, and particularly important to high-end gaming computer systems, which typically utilize high performance, and hotter running, components. Therefore, it would be desirable to have a computer system housing that protects accessible componentry while providing an aesthetically pleasing appearance.

Front panel 105 includes left door 110 and right door 120 for covering an opening in computer system housing 100. It should be appreciated that the pair of doors may also be referred to herein as a first door and a second door, wherein either the first door or the second door may be referred to as left door 110 or right door 120. The terms left door and right door are used herein for simplicity and understanding. In one embodiment, front panel 105 also includes venting 112, for providing airflow to electronic componentry within computer system housing 100. In one embodiment, the opening is for providing access to electronic componentry of the computer system. As shown in FIG. 1, left door 110 and right door 120 and right door are in a closed position. While in the closed position, left door 110 and right door 120 provide protection to electronic componentry in the opening, and prevents user access to the electronic componentry.
Left door 110 is movably coupled and opposably slidable to right door 120 such that a single action to open one of left door 110 or right door 120 is operable to open the other door by sliding the other door in a substantially opposite direction. For example, a single action by a user to open left door 110, as indicated by arrow 130, is also operable to open right door 120 in the opposite direction, as indicated by arrow 140. Similarly, a single action by a user to open right door 120, as indicated by arrow 140, is also operable to open left door 110 in the opposite direction, as indicated by arrow 130. In other words, a single action to open one door causes the other door to open simultaneously. In one embodiment, the single action is a user pulling one of the doors from a center of the opening to an outer edge of the opening.
FIG. 2A is a left side perspective diagram of computer system housing 100 with left door 110 and right door 120 in an open position, in accordance with an embodiment of the present invention.
