NANO CAIXA 104 Modular System

Portable 104HP Eurorack Case With Built-In Utilities

The NANO CAIXA 104 is a fully portable 104HP Eurorack case designed to remove the most tedious part of building a modular system: buying the boring utilities. Instead of spending HP on multiples, mixers and output stages, this 3U enclosure ships with seven essential modules already integrated into the busboard, leaving all 18 module slots free for oscillators, filters and the sound-design modules that matter to your patches. The CAIXA 104 is the right choice for players who want a complete, gig-ready Eurorack system in a single grab-and-go box without sacrificing headroom, I/O flexibility or depth for modern modules.

What Sets the CAIXA 104 Apart

Most portable cases ship empty and force the user to populate them with 1U utility modules before a single patch can be made. The CAIXA 104 inverts that equation by hard-wiring a precision adder with two CV inputs and an octave rotary switch spanning -2 to +5 octaves, two active 1-to-3 buffered multiples, a sample-and-hold stage with its own white-noise output, two LFOs with triangle and square waveforms, and a 2-channel stereo mixer with master volume. The result is a self-contained performance instrument: balanced 6.3 mm TRS inputs with 20 dB of gain, balanced TRS stereo outputs, a 3.5 mm headphone jack with its own level control and a Meanwell 60W external power brick matched to your region's socket.

Power Supply and Electrical Capacity

Headroom matters in a portable case, and the integrated switching PSU is sized for real-world patches rather than minimal demos. The regulated 15V internal rail keeps the supply stable.

• External Power Brick: 60 W Meanwell — region-specific mains adapter included with the case
• Internal Switching PSU: 30.7 W with regulated +15V rail
• Current Capacity: +12 V @ 1.25 A · -12 V @ 1.1 A · +5 V @ 0.5 A — enough headroom for up to 18 modules

Inputs, Outputs and Onboard Utilities

The integrated 1U row is what makes this case feel like an instrument rather than a chassis. Every utility you would normally patch in from outside is already there, normalized and ready, so the front panel stays clean.

• Balanced Inputs: 2 × 6.3 mm TRS with up to +20 dB of gain and a level meter — perfect for routing external audio into the rack
• Buffered Multiples: 2 active 1-to-3 splitters — preserve CV pitch when fanning out to several destinations
• Precision Adder: 2 CV inputs, 2 sum outputs, octave rotary switch -2 to +5 — calibrate offsets and transpose sequences in real time
• LFOs: 2 with triangle and square outputs and rate control — modulation sources for movement and clocking
• Sample & Hold: with dedicated white-noise output — random CV generation without buying an extra module
• Stereo Mixer and Outputs: 2-channel mixer, balanced 6.3 mm TRS stereo out, 3.5 mm headphone jack with volume, master volume

Physical Construction and Portability

The chassis is built for the road, not just the desk. Anodized aluminum panels paired with extruded rails and steel threaded inserts give the rails the strength to hold heavy modules through years of transport, while rubber feet protect the work surface when the case is parked at home.

• Dimensions (W × D × H): 535 × 200 × 86 mm — desktop-friendly footprint that still fits a full 104HP row
• Module Depth: 47 mm above the busboard · 60 mm outside busboard space — accommodates the vast majority of contemporary modules
• Weight: 1.7 kg — light enough to carry one-handed with the integrated handle
• Materials: anodized aluminum panels, extruded aluminum rails with steel threaded inserts, rubber feet
• Package Contents: CAIXA 104 case, external AC power supply

Who the CAIXA 104 Is For

The CAIXA 104 is the right choice for newcomers stepping into Eurorack who want a complete, working system on day one without researching which 1U utilities to buy first. It is also a strong fit for performing electronic musicians who need a compact, road-worthy case with balanced I/O, headphone monitoring and a built-in mixer that can be taken straight to a venue or a friend's studio. Compact-rack builders who want to add a portable performance unit alongside a larger studio rig will appreciate the 104HP width, the 60 mm of outside-busboard depth for deep modules, and the integrated handle that makes one-handed transport realistic. Players who prefer to swap utility modules frequently, or who want to install Ornament-and-Crime-style 1U tools, should note that the integrated row is fixed and not user-replaceable.

NANO Modules — Designed and Built in Spain

NANO Modules is a Spanish synthesizer company based in the Valencia region, focused on compact, performance-oriented Eurorack hardware that pairs clean industrial design with practical, road-ready engineering. The CAIXA 104 reflects that philosophy: a portable 104HP enclosure with the utilities already integrated, a Meanwell power section chosen for reliability, and an anodized aluminum chassis built to survive regular transport rather than sit permanently on a studio desk.
