Foundation

Your home server with integrated productivity software. Email, files, calendar, and notes that actually work together on hardware you own.

Figure 01. Foundation Chassis

Physical

Milled from a single block of 6061-T6 aluminum. The unibody chassis acts as a passive heatsink, eliminating fan noise and dust accumulation.

Compute

Powered by efficient x86 architecture using Intel N100 series processors. Expandable LPDDR5X memory and PCIe Gen 3.0 backplane for future-proofing.

Logic

Shipping with CornerstoneOS, an integrated environment where your email, files, calendar, and notes share context. Search once, find everything—all running locally on your hardware.

Universal Architecture

Six identical bays. Infinite configurations.

The System

Each Foundation unit features six universal module bays, accessible from the chassis front. Hot-swappable by design, these bays accept standardized modules that communicate directly with the PCIe Gen 3.0 backplane.

No tools. No reboots. Reconfigure your system as your needs evolve—swap a storage module for network expansion in seconds.
