- 80% layout with a top-mount case.
- KBDfans lists compatibility with Realforce R1 86/87/88/89u internals and Cipulot’s RF_R1_8-9Xu PCB.
- The vendor lists WK and WKL options and compatibility with R1 and R2 OEM PCBs through custom JST cables.

- No numpad.
Pick the Athena 75 if you want a ready-to-configure DIY kit with hot-swap, multiple plate materials, RGB, and VIA/VIAL support. Choose the RF 8X when your priority is its Realforce R1-family and custom EC compatibility, and you are comfortable with soldered switches or a compatible replacement PCB. Check the RF 8X's specific internals compatibility before buying, since it is not presented as a general-purpose hot-swap board.

What will you mostly use it for?
The Athena 75 is the more adaptable choice across the listed everyday categories, particularly for buyers who want hot-swap, lighting, and firmware options. Its smaller layout gives it an edge for travel, though the listed weight is substantial and the RF 8X also includes a carrying case. The RF 8X's strongest case is specialized: it provides a top-mount enclosure for selected Realforce internals and custom EC builds. Buyers without that specific project in mind have more build flexibility with the Athena 75.
Pick the KBDFans Athena 75
- The Athena 75 has a hot-swappable PCB and supports VIA and VIAL.
- It offers RGB and a choice of aluminum, FR4, polycarbonate, or carbon-fiber plates.
- The RF 8X listing specifies compatibility with selected Realforce internals and a Cipulot PCB, rather than a general-purpose hot-swap build.

KBDFans Athena 75 vs RF 8X: your questions
Yes. The Athena 75 metadata lists hot-swap, and KBDfans describes solder, hot-swap, and RGB hot-swap PCB options. The RF 8X metadata says its switches are soldered, so changing them requires soldering.
No, its compatibility rules specify that switches are soldered and swapping them means soldering. The vendor does describe optional custom PCBs, including a Via-supported PCB, but the listed RF 8X build is not a hot-swap board.
The Athena 75 is a 75% DIY keyboard kit with hot-swap, RGB, VIA/VIAL support, and several plate choices. The RF 8X is an 80% top-mount case focused on compatibility with specified Realforce internals and custom EC components.
Yes. Both the Athena 75 metadata and KBDfans listing specify VIA and VIAL support. KBDfans also lists PCB-specific VIA V3 files for its solder, hot-swap, and RGB hot-swap PCB variants.
KBDfans lists compatibility with Realforce R1 86/87/88/89u internals for both WK and WKL versions. The vendor also describes R1 and R2 OEM PCB compatibility through custom JST cables, so check the exact internals and configuration before purchasing.
The Athena 75 lists RGB and its vendor page describes an RGB hot-swap PCB layout. The RF 8X metadata lists no RGB.
Both listings identify a screen: the Athena 75 has an LCD screen, while the RF 8X has an LED screen. The available descriptions do not establish that their screen functions are the same.
The Athena 75 is a 75% layout, while the RF 8X is an 80% layout. The Athena 75 is therefore the more compact layout by the listed size category, though its metadata gives a built weight of 2300g.
The Athena 75 metadata lists aluminum, FR4, polycarbonate, and carbon-fiber plates. KBDfans also describes a plateless build option when using the solderable PCB.
The RF 8X vendor page identifies compatibility with Cipulot’s RF_R1_8-9Xu PCB and describes optional custom PCB upgrades, including a Via-supported PCB. It also names compatible Realforce OEM internals, so verify the PCB and internals match your intended build.
KBDfans lists a carrying case among the Athena 75 kit contents and a protective carrying case among the RF 8X contents. The Athena 75 listing also includes a keyboard cover.
Neither model has a numpad, according to their compatibility rules. The Athena 75 is a 75% layout and the RF 8X is an 80% layout.
