It reuses its motherboard MNT Station turns a Reform laptop motherboard into a desktop or server. Its modularity matters most when it creates a real migration path for hardware that still works. When a modular laptop gets a new motherboard, one very physical question arrives with the upgrade: what happens to the old one? It still works. It still contains a processor, memory, ports and perhaps storage. It simply no longer has a convenient screen, keyboard or enclosure around it. MNT Research built **MNT Station** around that exact moment. The new device is more than an open-hardware mini PC: it is a desktop enclosure compatible with classic MNT Reform motherboards 2.0, 2.5 and 3.0, allowing a board removed from a laptop to become a desktop, home server, router or edge machine.[1](https://www.crowdsupply.com/mnt-research/mnt-station) Modularity suddenly becomes much less abstract. The upgrade extends the primary computer, then the removed board can start a second machine instead of waiting on a shelf. ## Move the board Station makes the most sense when a Reform already exists. Upgrade its motherboard, then move the previous one into Station.[1](https://www.crowdsupply.com/mnt-research/mnt-station) The enclosure measures **279 × 133 × 26 mm**, under one litre in volume, and can lie flat, stand on its long edge, attach to VESA 75 × 75 or 100 × 100 mounts, or hang directly on a wall.[1](https://www.crowdsupply.com/mnt-research/mnt-station) Two SMA panel openings allow radio antennas to sit outside the metal case. Changing the form already opens different jobs. A motherboard designed to live beneath a laptop keyboard can end up behind a monitor, inside a network cabinet or on a wall beside other homelab hardware. > MIGRATION > **One board, two lives** > - the Reform receives a newer motherboard: 1 > - the old board still works: 2 > - Station gives it enclosure and port access: 3 > - it becomes desktop, server or router: 4 > Modularity becomes more credible when the replaced part keeps a complete use. That continuity has very clear limits. Station is built around the Reform ecosystem and its geometry. The migration works because MNT deliberately preserves interfaces across generations of its boards. ## CPU as module Inside the enclosure, the Reform motherboard splits the problem once again. A **200-pin connector** accepts a Processor Module carrying CPU, memory and sometimes eMMC.[1](https://www.crowdsupply.com/mnt-research/mnt-station)[4](https://mntre.com/documentation/reform-handbook/hardware.html) MNT offers modules around Rockchip RK3588 and NXP LS1028A, plus an adapter for Raspberry Pi Compute Module 4.[1](https://www.crowdsupply.com/mnt-research/mnt-station) It even publishes a KiCad template for designing other processor and memory combinations around the connector.[5](https://source.mnt.re/reform/reform-som-template) This moves away from the usual mini PC where CPU and RAM permanently belong to the same board. Here enclosure, motherboard and processor module are separate layers. > **Three replaceable layers** > Diagram showing the MNT Station enclosure, Reform motherboard and processor module as separate layers > - The enclosure is not the motherboard; the motherboard is not the CPU > - STATION ENCLOSURE · mechanics + mounting + ports > - REFORM MOTHERBOARD · power + I/O + PCIe > - CPU + RAM MODULE > An upgrade path does not require all three layers to be replaced together. Motherboard 3.0 adds USB-C Power Delivery, increases the NVMe slot to as many as four PCIe lanes with RK3588, modernises parts of the power system and exposes Qwiic/I²C connectors.[3](https://shop.mntre.com/products/mnt-reform-motherboard-30)[4](https://mntre.com/documentation/reform-handbook/hardware.html) It also retains mini-PCIe and M.2 Key M expansion.[1](https://www.crowdsupply.com/mnt-research/mnt-station) The port list matters less than the boundary between responsibilities. Replacing CPU and RAM does not automatically require a new enclosure or motherboard. ## Actually open “Open hardware” can become vague when it means little more than a schematic somebody can download. The MNT Station repository goes further.[2](https://source.mnt.re/reform/mnt-station) It contains KiCad projects for port boards, **STEP** and **STL** files for enclosure parts, and a **FreeCAD** assembly. The README licenses the material, except where individual files say otherwise, under **CERN OHL-S 2.0**.[2](https://source.mnt.re/reform/mnt-station) A user can inspect the electronics, alter a port cover, remake a mechanical part or start a derivative directly from the published files. The CNC-milled aluminum enclosure sold by MNT is therefore not the only possible physical form of the design. For a product built to extend the life of other modules, publishing the mechanics too avoids an obvious contradiction. A sealed enclosure with inaccessible mechanical sources would create a new dependency at the same moment the project tries to remove one. ## What $299 buys The campaign starts at **$299** for the enclosure. That figure can easily look like the price of a complete computer. It is not.[1](https://www.crowdsupply.com/mnt-research/mnt-station) The base kit includes aluminum case parts, one electronic port cover with power button, ATtiny microcontroller and a bar of ten controllable LEDs, a second port cover and mounting screws.[1](https://www.crowdsupply.com/mnt-research/mnt-station) Reform Motherboard 3.0, processor module, SSD, Wi-Fi hardware and even the power adapter are separate from the standard case.[1](https://www.crowdsupply.com/mnt-research/mnt-station) Any **65–100 W USB-C PD** adapter should work, but it still needs to exist. Wi-Fi also requires the module, possible adapter, cables and antennas. The separation fits a modular platform. It also makes simple price comparisons with assembled mini PCs rather shaky. > $299 > **That is the chassis price** > - aluminum, port covers, button, LEDs, screws: Included > - motherboard + CPU/RAM module if none is being reused: Add > - SSD, Wi-Fi, antennas, power adapter: By use > - reuse hardware you already own: Real leverage > The economics make the most sense when Station receives Reform hardware that has already been paid for. Station therefore makes more sense as a **destination for existing hardware** than as a shortcut to the cheapest new computer. ## Fanless, but ARM MNT lists an RK3588 configuration at roughly **20 W average power** in its own comparison and uses fanless cooling with a heatsink.[1](https://www.crowdsupply.com/mnt-research/mnt-station) That suits a quiet home server or a machine mounted behind a screen. The 20 W figure comes with an architectural choice rather than for free. Promoted configurations are primarily ARM systems, with Debian on the complete system.[1](https://www.crowdsupply.com/mnt-research/mnt-station) A homelab built around x86-only images or proprietary x86-64 software may care more about that difference than about enclosure volume. Modularity also cannot erase I/O limits. Ethernet is Gigabit, and DisplayPort capability on the optional dual USB-C board depends on the processor module in use.[1](https://www.crowdsupply.com/mnt-research/mnt-station) Those compromises fit the target machine and keep “future-proof” from turning into magic. Hardware remains upgradeable only inside the interfaces and performance envelope its architecture actually exposes. ## Future stacks Pass-through openings and geometry on the enclosure are intended for **future stackable expansions** such as battery/UPS modules, hard disks or a GPU.[1](https://www.crowdsupply.com/mnt-research/mnt-station) The word to keep is “future.” Those modules are not yet a mature catalogue of shipping products. Battery support does build on an existing Reform capability: monitoring and charging eight LiFePO4 cells with an open Linux driver, provided the required holders, protected battery boards and cables are added.[1](https://www.crowdsupply.com/mnt-research/mnt-station)[4](https://mntre.com/documentation/reform-handbook/hardware.html) There is a useful difference here between designing for extensions and already having an extension ecosystem. The first already exists in holes, connectors and pass-throughs. The second still needs to be manufactured, documented and delivered. ## The useful leftover “Compact open-source desktop” is accurate, but it misses the rarer part of the project. Most modular computers answer “how can one part be replaced without discarding the whole machine?” Station adds another question: **what happens to the replaced part when it still works?** Its answer is not universal. It depends on an ecosystem that is specific in geometry even when its sources are open: Reform boards, Reform module connector, Reform dimensions. The principle travels further than the product. Repairable architecture becomes more interesting when it plans how the new part enters and where the old one can go next. In that sense the $299 aluminum enclosure is almost the least important piece. The real product is a **hardware migration path** that can turn one laptop upgrade into the birth of a second computer. ## References 1.
