The Venturi — a sub-11-litre watercooled desktop, front elevation

Nothing short of perfection is acceptable.

The Vision

The Optimist Venturi represents a cumulative 150 years of PC-building prowess by our team. Built on the legacy of the FormD T1, one of the best small-form-factor cases of all time, it takes that foundation and refines it past the limits of what an off-the-shelf chassis can do.

Featuring over 20 custom modifications to water-cool and expand the chassis, the Venturi runs cooler, quieter, and harder than its footprint should allow — proof that thermal performance and form factor were never meant to be a trade-off.

Watercooled CPU, GPU, SSD, and RAM

Cooling NVIDIA's most powerful Blackwell GPU inside a sub-eleven-liter chassis means building the cooling from the ground up. The 600R platform, designed for Venturi, runs a triple-radiator, full-copper watercooling loop with 600mm of radiator surface, powered by a dedicated CPU pump-block.

At its core, an 80ml reservoir is seated above the SSD and RAM. As coolant moves end to end, it draws heat off the storage and memory directly, holding throughput steady during sustained high-speed transfer loads.

Intake Side

Home to the motherboard and power supply. The top radiator fans pull air through the side mesh, drawing it across every core component. The power supply breathes the same direction — in through the side, out through the floor. One path, one pressure gradient, no dead air.

Ceramic-Coated Badged CPU Block

A solid brass block, ceramic-coated for corrosion resistance and finished with an engraved Optimist badge bonded in thermal adhesive so heat transfer stays uninterrupted.

Venturi was designed to condense as much power as feasible into as low a volume as possible. In this, it excels. Compared to the newest-generation, fully-contained, commercially-available systems, Optimist takes both first and second place — the Venturi dominating in both raw compute power and density (measured by maximum TDP in watts ÷ volume in liters).

Fully-contained systems are defined as self-supporting and without need for external PSU, GPU, radiator, or any other part critical to the PC's everyday functionality. Systems that run unsuitable cooling systems for the appropriate hardware are not included or recommended for use.
