10" Rack 3U 4x 3.5" + 6x 2,5" HP Gen8/9 HDD Module

Follow the collection for new rack modules and updates This is a 3U rack module for 4× 3.5" drives and 6x 2.5" drives, designed specifically for short-depth HP-style caddies, solving a common issue with existing designs that require extra depth to fit standard trays. Most available solutions need additional clearance behind the drives, making them unsuitable for compact racks or shallow enclosures. This version is optimized to fit shorter caddies while maximizing storage density in a compact 10-inch rack. Additionally, I have designed compatible 3D printable caddies, allowing you to build a complete storage system even if you don't have original HP Gen8/Gen9 caddies. Key Features ✅ Holds 6× 2.5" SATA/SAS drives and 4× 3.5" SATA/SAS drives ✅ Designed for short-depth HP-style caddies ✅ Compatible with HP Gen8 and Gen9 drive caddies ✅ Compatible with my 3D printed HP-style caddies 3.5" Files here and 2.5" Files here ✅ Space-efficient 3U design ✅ Strong and rigid construction ✅ Perfect for compact homelab storage servers     Boost MeIf you found this model usefull consider giving it a boost  Why this model? Existing drive cages often require more rack depth. Many designs are incompatible with short HP-style caddies. This module maximizes storage capacity while remaining compact.
