CWWK F18 / F20 Firewall Mini PC, Intel 12th / 13th Gen Core i3-1315U i5-1335U i7-1355U, 6 × Intel i226-V 2.5GbE LAN, DDR5, Dual NVMe, USB4 Type-C, OPNsense Router PC

The CWWK F18 / F20 is a high-performance 6-port 2.5GbE firewall mini PC designed for OPNsense, pfSense, OpenWrt, Proxmox, VPN routing, small office networking, and advanced home lab use. Both F18 and F20 use the same motherboard platform, with the main difference being the chassis and cooling design. Users can choose the F18 flagship aluminum chassis for a more compact and premium build, or the F20 larger chassis with built-in fan cooling for heavier workloads and stronger thermal headroom.

Same Core Hardware Platform, Two Chassis Options:

The F18 and F20 share the same motherboard design, CPU platform, networking configuration, memory support, storage expansion, and I/O layout. The F18 uses a flagship aluminum chassis with a compact premium design, while the F20 uses a larger chassis with an internal fan to provide better airflow for users who plan to run heavier workloads for long periods.

Intel 12th / 13th Gen Core Processor Options:

The CWWK F18 / F20 supports Intel Core i3-1315U, Core i5-1335U, and Core i7-1355U processor options. Compared with entry-level N-series firewall mini PCs, these Core U-series processors provide stronger performance for virtualization, VPN, Docker, network monitoring, firewall services, and multi-role home lab or small office deployments.

6 × Intel i226-V 2.5GbE LAN Ports:

With six Intel i226-V 2.5GbE network ports, the F18 / F20 is suitable for multi-WAN routing, VLAN segmentation, VPN gateway, firewall deployment, NAS networking, wireless AP backhaul, and isolated office networks. The 6-port design gives users more flexibility than standard 4-port firewall appliances, especially when separate WAN, LAN, guest, IoT, NAS, and lab networks are required.

DDR5 Memory and Flexible Storage Expansion:

The F18 / F20 supports DDR5 memory for better bandwidth and system responsiveness. It also provides dual M.2 NVMe storage and SATA expansion, making it practical for Proxmox, Linux services, firewall logs, lightweight NAS use, local applications, and multi-system environments.

USB4 Type-C and Multi-Display Output:

The Type-C USB4 port supports high-speed data transfer and display output, while HDMI and DisplayPort provide additional display connectivity. This makes the system convenient for setup, monitoring, troubleshooting, or desktop-style use when needed.

Choose F18 for a Premium Compact Build, F20 for Stronger Cooling:

The F18 is recommended for users who prefer a cleaner flagship aluminum chassis and a more compact hardware appearance. The F20 is recommended for users who want a larger chassis with built-in fan cooling, especially for Core i5 / Core i7 configurations, virtualization, VPN, Docker, or heavier 24/7 workloads.

Built for Firewall, Virtualization, and Network Services:

Whether used as an OPNsense firewall, pfSense router, OpenWrt soft router, Proxmox host, VPN gateway, VLAN router, small Linux server, lightweight NAS gateway, or edge network appliance, the CWWK F18 / F20 provides a strong balance of performance, multi-port networking, storage flexibility, and reliable operation.
