3D-Printed Retro PC Case Brings Old-School Tower Style to Mini-ITX Builds

A beige-box throwback has turned into a print-it-yourself mini-ITX project, and the files are already out in the wild. An enthusiast known as u/Potatozeng shared photos of the retro-style case on r/3Dprinting and posted the design for others to print, with the model credited as Retro Style Mini-ITX PC Case by PuTaTuo on Printables and Thingiverse. The appeal is immediate: the look of an old desktop tower, but sized for a modern compact build that can actually sit on a desk and run daily tasks.

The practical side is what makes the design more than a nostalgia piece. Printables shows 18 files and an instruction PDF, with the files updated on March 10, 2025. The build breaks down into 17 separate 3D files that assemble into 20 parts and panels, and the creator says printing everything took about 85 hours. The Thingiverse listing says the case supports a Mini-ITX motherboard and an ATX-size power supply, with every part kept under 220 mm. That makes the project manageable for many home printers, but not trivial, especially once assembly starts.

The tradeoffs are just as clear. The MakerWorld listing says the case accepts an air cooler up to 50 mm tall and includes one 3.5-inch front bay that can be used for front I/O or a floppy drive. It also lists a bill of materials that goes well beyond plastic: heat-set inserts, M3 screws, 5 mm LEDs, mechanical keyboard switches, female jumper cables and wires all show up in the parts list. The creator also calls for super glue and a soldering iron, and the instruction PDF with photos is meant to keep the build approachable despite the electronics work.

That compact layout comes with real limits, though. Unlike SilverStone Technology’s FLP01, which was first revealed at Computex and later launched as a retro remake of the GD09 HTPC design, the printed case does not leave room for a discrete graphics card, even a low-profile one. It also skips a dedicated 2.5-inch drive mount, pushing builders toward a SATA SSD mounted above the PSU. In practice, that makes the case best suited to lighter gaming rigs or office PCs rather than power-hungry hardware, but it also gives the community something rarer: a functional retro tower that ordinary makers can print, assemble and actually use.
