Geerling’s guide aims to save everybody a whole lot of Reddit reading, question-asking, and blind-faith-buying as they get started or seek to expand their rack. Most 10-inch, or “half-width” racks (despite the “standard” rack being 19 inches wide) have only a few major manufacturers, and their availability varies by country. Each type of device that fits into the mini rack—power distribution units (PDUs), uninterruptible power supplies (UPS), HDD-sized shelves—gets linked by Geerling, along with important specs. There are also links to 3D-printable rack systems, cable management ideas (harder on a half-size setup than full), and showcases of mini racks of note.
Geerling’s page acknowledges the collective efforts of communities like Reddit’s /r/minilab have put into the burgeoning half-size market, long before his project. But seeking a central compendium, Geerling compiles gear, tips, and compatibility advice for mini-builds, along with ongoing discussions about the merits of individual components and broader build-out strategies.
“The community feedback around Project Mini Rack has been great so far,” Geerling wrote in an email to Ars. The 3D-printed links and suggestions have been showing up steadily since he started committing to the page in earnest in mid-January. He’s particularly excited to see that a “LACK rack,” or using IKEA shelving for budget rack mounting, can be downscaled to mini-rack size with an Edet cabinet. “It’s like someone at IKEA is a Homelab enthusiast,” says Geerling.
This post was updated to better define homelabs and minilabs.
