What makes the HP Extras Class 1800 Southpaw unique compared to standard keyboards?

The HP Extras Class 1800 Southpaw stands out with its left-handed (Southpaw) numpad layout, making it ideal for users who prefer or require the numpad on the left side. This design improves ergonomics for left-handed typists and can enhance workflow efficiency for specific tasks.

Does the keyboard support different mounting styles?

Yes, it features both top mount and silicone bottom with gasket mounting options. This flexibility allows users to tailor the typing feel—whether you prefer a firmer or more cushioned experience, the Class 1800 Southpaw can accommodate your preference. It also supports plateless builds for an even softer typing sensation.

What is the keyboard made of?

The case of the Class 1800 Southpaw is crafted from high-quality 6063 aluminum, offering both durability and a premium feel. Inside, it includes a brass weight treated with an antioxidant finish to maintain its appearance and heft over time.

Is the PCB compatible with custom firmware?

Absolutely. The keyboard features a QMK- and VIAL-compatible PCB, which means you can fully customize keymaps, macros, and layers through open-source firmware. This makes it an excellent choice for enthusiasts who want to tweak every aspect of their keyboard.

How heavy is the Class 1800 Southpaw keyboard?

Unbuilt, the keyboard weighs approximately 3.5kg, and when fully assembled, it reaches around 4.2kg. This substantial weight not only gives the keyboard a solid, premium feel but also ensures stability on your desk during intense typing sessions.

Can I use the keyboard for both work and gaming?

Definitely! With its robust construction, customizable firmware, and ergonomic layout, the Class 1800 Southpaw is suitable for both professional work environments and gaming setups—especially for users who appreciate a left-side numpad.

What layout options are available for this keyboard?

The Class 1800 Southpaw comes in several layout variants, including WK (standard with Windows keys), HHKB (Happy Hacking Keyboard-inspired), and WKL (without Windows keys). This allows you to choose a layout that best fits your typing style and preferences.

Is the plate or PCB customizable after purchase?

The keyboard comes with fixed PCB and plate options. While you can customize keycaps and switches, the PCB and plate are specific to this model and are not designed for swapping with other types.

Is the Southpaw layout difficult to adapt to if I’m used to a standard keyboard?

While there may be a short adjustment period, many users find that switching to a Southpaw layout quickly becomes intuitive, especially for left-handed users or those who frequently use the numpad. The ergonomic benefits can be significant for those who take the time to adapt.

What kind of typing angle does this keyboard offer?

The Class 1800 Southpaw features a 7° typing angle, which is designed to promote a more natural wrist position and reduce strain during extended typing sessions.

Product Description

The HP Extras Class 1800 Southpaw is a high-mass, customizable mechanical keyboard kit designed for users who prefer a left-handed layout. It suits hobbyists and enthusiasts who want to build and program their own keyboard with flexible mounting options and advanced firmware support. This board is appropriate for those who value a solid typing platform and extensive customization but are comfortable assembling a keyboard from parts.

Key Features

Southpaw layout optimized for left-handed users, offering a unique key arrangement not commonly found in standard keyboards.
QMK-VIAL firmware support allows deep customization of keymapping and macros, enabling tailored workflows.
Supports both top mount and silicone bottom with gasket mounting, giving users control over typing feel and sound by adjusting keyboard flex and damping.
Plateless design support provides additional typing feel customization by removing the plate that holds switches in place.

Build Quality

Constructed with a 6063 aluminum case, providing a sturdy and durable frame.
Includes a brass inner weight treated with an antioxidant to add heft and reduce vibrations, contributing to a stable typing experience.
Heavy overall weight (~4.2 kg built) ensures the keyboard stays firmly in place during use.
Prototype PCB may have functional variations compared to final group buy units, which could affect reliability or feature completeness.

Typing Experience

Mounting options and plateless support allow users to fine-tune acoustics and keypress feel, useful for those who want a specific typing sound or feedback.
Weight and materials contribute to a solid, less flexible typing surface, which some users may prefer for stability.
Unknown switch compatibility and sound profile details, as these depend on user-installed switches and keycaps.

Trade-offs

Southpaw layout limits compatibility with standard keycap sets and may require custom keycaps or modifications.
Prototype PCB status means some functions might vary or be incomplete, which could affect user experience.
Heavy weight and aluminum construction reduce portability, making it less suited for mobile use.
No wireless connectivity; this is a wired keyboard only.
