Shared Motherboard Platform Across S1, S2, S6 and S8
CW-S1, CW-S2, CW-S6 and CW-S8 use the same core motherboard platform. Their primary differences come from the enclosure, physical dimensions and cooling design rather than the underlying network and expansion architecture.
Shared Core Platform
The four models share the same dual 10GbE SFP+, dual 2.5GbE, DDR5, NVMe and SATA architecture.
S1 Flagship Chassis
CW-S1 uses the larger flagship enclosure with its own physical layout and active cooling configuration.
S1 Flagship Aluminum Chassis
CW-S1 uses CWWK's flagship aluminum enclosure measuring 178 × 145 × 58 mm. The larger footprint provides additional internal space for the shared motherboard platform, storage expansion and active thermal components.

Flagship Chassis
Aluminum Enclosure
Dual-Fan Active Cooling for Sustained Network Workloads
CW-S1 uses an active cooling structure with two CPU cooling fans together with the aluminum chassis to manage system heat during sustained firewall, routing and high-speed networking workloads.
CPU Fan 1
Provides active airflow for the internal processor and thermal structure.
CPU Fan 2
Works alongside the primary fan to improve internal airflow and heat removal.
Aluminum Chassis
The enclosure provides additional external surface area for overall thermal dissipation.
2.5-Inch SATA SSD and HDD Expansion
CW-S1 provides a SATA 3.0 interface and 4-pin SATA power socket for installing a compatible 2.5-inch SATA SSD or HDD inside the chassis.
2.5-Inch SATA Storage
Add a compatible 2.5-inch SSD or HDD for additional local storage.
Data + Power Connection
The motherboard provides both SATA 3.0 connectivity and a dedicated 4-pin SATA power socket.
VESA Mounting for Flexible Installation
CW-S1 supports VESA mounting for installations where desktop space is limited or where the system needs to be mounted behind a compatible display or on a suitable mounting surface.
VESA Mounting
Supports compatible VESA installation for more flexible system placement.
Space-Saving Deployment
Suitable for compact workspaces, network stations and other installations where desktop space is limited.
Firewall, Routing and Home Lab Deployment
The combination of dual 10GbE SFP+, dual 2.5GbE Ethernet and multiple Intel N-Series processor options makes CW-S1 suitable for a wide range of network appliance deployments.
Firewall Appliance
Build multi-gigabit firewall and gateway systems using dedicated SFP+ and RJ45 interfaces.
10GbE Routing
Use SFP+ connections for high-speed routing, uplinks, aggregation or links to compatible switches and servers.
Home Lab
Deploy routing, VPN, VLAN, virtualization and other x86 network services from one compact platform.
Front and Rear I/O Connectivity
CW-S1 combines dual 10GbE SFP+, dual 2.5GbE Ethernet, display, USB, storage and expansion interfaces within the flagship chassis.
