Compact RISC OS Powerhouse with Room to Grow The DIY TWO is a mid-range self-assembly RISC OS computer kit designed for those who want a little more connectivity and expandability than the smaller DIY ONE, while still keeping the build process straightforward. Supplied with all essential parts except for the power supply, the kit includes a laser-cut oak-veneered MDF case, a Raspberry Pi Compute Module 4 with heatsink, a dedicated carrier board, a 128 GB NVMe drive, a 32 GB eMMC module, and the necessary standoffs, spacers, screws, and washers to put everything together. Each case panel is delivered with protective film to prevent damage during handling and is supplied untreated, allowing you to finish it to your own preference. Assembly is simple and requires only basic tools. The process begins with preparing the Compute Module 4 by fitting thermal pads and attaching the heatsink. The module is then installed onto the carrier board, followed by the NVMe drive and eMMC module. The board is mounted onto brass standoffs inside the case, with spacers used to align the structure, before the side panels, end plate, and top cover are secured. The top cover can be removed easily, allowing for straightforward access to the internals for upgrades or maintenance. The DIY TWO offers a compact footprint of around 140 mm by 120 mm, yet includes four USB ports, HDMI output, Gigabit Ethernet, and both USB-C and barrel jack power options. With a 2 GHz CPU, 2 GB of RAM, and dual-tier storage, it provides a capable RISC OS system that can be tailored to suit your needs. The modular design ensures that components can be replaced or upgraded in the future, making the DIY TWO a flexible and long-lasting choice for those who want hands-on involvement in building their own system.
