Norco RPC-4220 SATA multiplier bracket

thingiverse

I've long enjoyed the Norco RPC-4220 case, which allows for 20 hot swap drives plus some internal drives. This setup is typically driven by a SAS HBA and a couple of hydra cables. However, a big SAS system will take a lot of power. My system takes very little power, using a low power CPU system with 6x SATA connectors to connect all 20 drives via 1x5 drive multipliers. This would be a huge bottleneck for a big, corporate, system but is more than sufficient for a home system that is CPU constrained running ZFS on an i3. What's more, it is extremely affordable. For several years, I let the drive multipliers rest on the motherboard inside the case. It wasn't a big problem but recently, after pulling the server from the rack for cleaning, I decided to design a bracket to hold the multipliers in place and neaten the wiring. This is a niche bracket, to be sure. If you need it, you know exactly what you're looking at. The FreeCAD project was designed in a recent daily build of FreeCAD being run on linux. The FreeCAD project is rapidly evolving into a powerful, stable, extensible, multi-platform, CAD tool that is freely available to anyone with an interest. Almost all of the reviews currently available of FreeCAD are dated and focus on problems that are long solved. To see a deep dive comparison of FreeCAD vs SolidWorks, check out "Joko Engineeringhelp" YouTube channel. He has fantastic comparisons of FreeCAD / SolidWorks / OnShape. He also does some deep dives into FreeCAD and SolidWorks comparing their finite element analysis features and more. His videos are dense with information and detail. All the resources needed to learn FreeCAD to an excellent level are available on YouTube and other sites. If you are interested in a powerful, open, cross-platform, CAD application, FreeCAD is the only choice. What's more, it's a viable choice.
