Precision-crafted 10-inch homelab rack system. Engineered in high-strength PETG with interlocking expandable uprights, quick-release grab handles, and a high-density side mounting grid.
Front Iso View
Standard 5U 10-inch desktop configuration showing front mounting ears and electric-blue corner braces.
Engineered specifically for mini PCs, Raspberry Pi clusters, 10" network switches, and custom homelab servers.
Stack additional 2U or 5U upright kits with steel-reinforced alignment pins to scale your stack anytime.
Precision pegboard side panels allow friction-lock and thumb-screw accessory mounting without disassembling the rack.
Formulated in heat-resistant PETG to withstand continuous 65°C server exhaust temperatures without structural warp.

Expand from 5U to 10U Without Rebuilding
Protect your initial homelab investment. When your network gear, Mini PCs, and storage drives outgrow 5U of vertical bay capacity, slot in the upright extension kit to double your usable rack units in under ten minutes.
Compact desktop footprint with integrated handles
Full stack capacity with dual side pegboard venting
How The Expansion Works
Remove the four M4 corner fasteners securing the top handle and upper PETG chassis bridge.
Insert the precision-extruded upright extension rails into the reinforced internal interlocking channels.
Reattach the top bridge assembly and slide in the extended 10U pegboard panels for added lateral rigidity.
All expansion kits include high-tensile steel mounting hardware and match your existing FlexRack electric-blue and matte-black PETG color accents.
Pegboard Utility Panels
Maximize your 10-inch enclosure density. Structural PETG side and rear panels turn unused chassis space into high-capacity mounting planes for mini PCs, drive cages, and power bricks.
Side-Mount Modular Interface
Pre-tensioned mounting slots lock accessories into position using toolless captive twist-pins with zero lateral play.
Browse MountsRear Cable & Fan Exhaust Bay
Rear pegboard integrates slotted 80mm/120mm fan bracket mounts and passthroughs for clean keystone terminations.
Standard 15mm Center Pitch
Symmetrical mounting grid engineered with reinforced chamfers for repeatable twist-lock accessory positioning without chassis deformation.
SBC & Mini PC Carrier Bay
Vertical and horizontal side-mounting brackets for Raspberry Pi 4/5, Radxa, and compact NUC nodes, preserving internal rack units.
Dual 2.5" SSD Quick-Sleds
Snap-fit dual drive brackets click into side panels with toolless release levers and vibration-dampening PETG contact points.
Integrated Wire Management
Perimeter tie-off points and pass-through raceways keep high-density patch cables flush against exterior panels for clean airflow.
