【Overview】A 3-bay 3.5-inch SATA/SAS compatible hard drive enclosure with an airtight airflow for efficient heat dissipation.
 
【Parameters】Can install 3.5-inch disks, backward compatible with 2.5-inch disks via adapter brackets.
               Can install a 90mm cooling fan
               . The back panel has 3 SATA data interfaces, one large 4D power interface, one XT30 power interface, and a 20-pin power module slot.
               The back panel has power indicator lights and hard drive read/write lights.
               Compatible with Huawei RH2288V3 and V5 hard drive trays.
               Four-layer PCB (size can be sampled free of charge). Impedance matching must be selected when ordering (free and subject to requirements).

[Introduction] This open-source project is relatively easy to build, and the cost is relatively low if you have all the necessary equipment. However, for a better chance of a successful completion, it is still recommended to read the following instructions.
 

Tools needed: Heating table (teppanyaki grill), soldering iron, recommended stencil cutter, 3D printer with a printing area of ​​at least 25cm x 25cm.
For some component purchase links, please refer to the attached document. (The original capacitors used are Panasonic Sanyo SVP series, which are relatively expensive; other capacitors of the same size and voltage can be used as substitutes.)

      Usage: Connect to the computer motherboard using three SATA cables, or connect to the hard drive enclosure using a RAID card and adapter cables.
      Powered by a PC power supply: No power module is required; connect a large 4D printer to the backplane (if the cable is not long enough, you can buy an extension cable).
      Powered by an external 12V power supply: A power module is required; input via an XT30 interface (round-port DC power supplies can be purchased with adapter cables). Power supply must be at least 12V. 8A.
 
Power module: Features a gold-finger pluggable structure for easy replacement
. Casing: FDM printing is recommended (6 layers top and bottom, 4 layers outer wall, fill thickness no less than 20%).
Assembly: Use M3×8 screws for the casing; the M3 length of the cooling fan mounting screws is calculated as fan thickness + 5mm.
