HPI SPS-BRACKET 3-SLOT Πίσω PCIE W

When building or maintaining a desktop PC or workstation, missing rear slot covers can compromise airflow and invite dust. The HP N83421-001 is a service-grade 3-slot PCIe bracket that fills the gap left by removed expansion cards, restoring a clean, protected rear panel. It is a direct replacement for HP systems but fits any standard ATX or micro-ATX case with full-height slots.

Key specifications

• Product type: Expansion slot bracket
• Number of slots: 3
• Slot compatibility: PCI Express (PCIe)
• Mounting position: Rear PC case
• Form factor: Full-height

Why choose it

This bracket is built from galvanized steel, offering high durability and resistance to rust. Its vented pattern helps maintain proper airflow while keeping dust out of unused expansion slots. It also provides physical security for the internal components by covering open slots that could otherwise allow accidental contact or debris entry.

Ideal use cases

• Replacing a missing or damaged rear bracket on an HP desktop or workstation
• Covering unused PCIe slots after removing a graphics card or other expansion card
• Improving dust protection in PCs used in workshops, offices, or industrial environments
• Restoring a tidy, professional appearance to the rear of a computer case

Good to know

This is a genuine HP service part (part number N83421-001), ensuring a precise fit and finish. It is a simple screw-in installation and requires no special tools. The bracket is full-height, so it is not suitable for low-profile or slim cases. For users who need to cover a single slot, HP offers other bracket variants, but this 3-slot version is ideal when multiple adjacent slots are unused.
