DETAILED DESCRIPTION

(7) In our computer case, the opening is dimensioned such that the screw that fixes the expansion card is easily accessible and can be easily mounted with an corresponding tool.

(8) To fix the screw, it must be accessible with a suitable tool such as a screwdriver. To make this possible, the described opening is cut out at an appropriate place in the computer case. Thus, the screw is easily accessible.

(9) It is preferred that the opening extends to the side wall of the computer case.

(10) In one example, the rear panel includes a vertically bent section for fixing a side cover. To reach the screw easily, the opening extends into the vertically bent section. Thus, the screw can be reached from this side with a screwdriver, for example, in direct alignment. The screwdriver does not have to be set at an angle.

(11) A strip may be arranged on the rear panel of the computer case between the slot field and the opening, wherein the strip is vertical to the rear panel. The strip may include a hole or a threaded hole so that a slot bracket of the expansion card can be fixed to the strip by screwing it such that the screw head points in the direction of the opening.

(12) To do this, the slot bracket is inserted through the opening into the case and placed on the strip so that respective provided holes are congruent. Such a strip facilitates the accessibility of the screw by its protruding position.

(13) The opening may be closed with a cover. The cover can close the opening in the computer case and may prevent, e.g., penetration of electromagnetic radiation, but also dust into its interior.

(14) Advantageously, the cover snaps into the computer case by a snap lock. To reach the screw when fixing an expansion card, the cover is opened without any further aids. So that the cover can be closed after the expansion card has been fixed in place, one form of the cover can have a notch for the screw with which the expansion card is fixed.

(15) A hole may also be provided in the cover, which can be used to additionally fix the closed cover with a screw.

(16) To further seal the opening, a seal may be attached to the cover. The seal meets the requirements for prevention of electromagnetic interference and electrostatic discharge.

(17) It is advantageous that the cover is designed such that it presses the slot bracket of the expansion card against the computer case when closed. Thus, the expansion card is fixed a second time in addition to the screw connection.

(18) The cover may be partially covered by a side cover of the computer case so that it can only be opened after removing the side cover. This serves as an additional protection of the cover in closed state and prevents the cover from being opened unintentionally.

(19) The cover may be hinged to the edge of the vertical strip facing away from the computer case and can be swivelled around it. The advantage of such an attachment is that the open cover is not hindering when fixing the screw, but can be swivelled to the side opposite the screw head.

(20) Attaching an expansion card to a computer case requires a multi-step procedure. First, the side cover of the computer case is opened. Then, the screw that secures the cover to the case is loosened. The cover can then be opened, e.g., by swivelling. The cover is opened so that the screw head is freely accessible. After opening the cover, the expansion card is inserted into a slot of the slot field. The slot bracket of the expansion card is placed on a suitable place of the computer case, for example, the strip. Then the expansion card is fixed by screwing the slot bracket to the strip. By closing the cover, the slot bracket is additionally pressed against the computer case or ideally the strip. After closing the cover, the computer case is closed again. The cover can also be fixed to the case with a screw. Then, the side cover of the computer case is closed again.

(21) Our computer cases and methods are explained in more detail below in an example based on drawings.

(22) Similar or apparently identical elements in the figures are marked with the same reference sign. The figures and the proportions in the figures are not to scale.

(23) FIG. 1 shows the rear panel 14 of a computer case 1 that contains a slot field 15 with four slots 2 for expansion cards 16. Next to the slots 2 a strip 3 is arranged vertically to the rear panel 14, in which four holes are cut out. On the side of the strip facing away from the slot field 15 there is an opening 4 in the computer case 1. In this example, expansion cards 16 are installed in the two upper slots 2 of the computer case 1. The cards 16 have curved slot brackets 5 protruding from the opening 4 and rest on the strip 3. Each slot bracket 5 is fixed by screwing it to the strip 3.

(24) Through the opening 4, which is recessed in a part of the rear panel 14 and a vertically bent section 17 for fixing a side cover 13 of the computer case 1, screws 6 that fix the expansion card 16 are easily accessible for the corresponding screwdriver as illustrated in FIG. 2.

(25) A cover 7 in the shape of a flap, as shown in FIG. 3, is available to cover the opening 4. The cover 7 is shaped such that it completely covers the recessed opening 4. It comprises a swivelling structure 8 that allows the cover 7 to be hung on the outer edge of the strip 3 by lugs provided for this purpose. The opening 4 can then be closed by swivelling as shown in FIG. 4. The cover 7 is attached to the computer case 1 when closed by two catches 9. Two holes 10 at the top and two holes 10 at the bottom of the cover 7 additionally allow the cover 7 to be fastened to the computer case 1 by screwing it. Four notches 11 allow the cover 7 to be closed even after the screws 6 that fix the expansion cards 16 have been attached.

(26) FIG. 5 shows that a side cover 13 of the computer case 1 partially hides cover 7. To open the cover 7 and easily reach the screws 6, the side cover 13 must first be removed.
