HP cache de fente

When a desktop PC or workstation loses a PCIe card, the empty slot becomes an open door for dust, electromagnetic interference, and disrupted airflow. This HP expansion slot cover closes that gap with a full-height galvanized steel plate, screwed firmly into any standard ATX or mATX chassis. It is the same type of part used in HP factory builds, so it matches the case finish and keeps the interior clean and cool.

Why choose it

This cover is not a universal afterthought; it is built to the same dimensions and finish as HP original case parts. The vented pattern helps maintain positive air pressure inside the case, while the steel construction blocks EMI that could affect nearby components. It resists rust and wear, so it will last as long as the chassis itself.

Ideal use cases

• Replacing a missing or damaged slot cover after removing a graphics card, sound card, or network adapter.
• Building or upgrading a PC with a standard full-height case that needs extra slot covers.
• Maintaining a fleet of office desktops where empty slots must be covered for safety and compliance.
• Reducing dust buildup in industrial or workshop environments.

Good to know

Installation takes less than a minute: align the cover with the slot opening, insert the screw (not included), and tighten. The cover is compatible with any standard full-height PCI or PCIe slot, regardless of brand. For low-profile or half-height cases, a different size is required.
