This massive 173% mechanical keyboard is a tribute to the classic space-cadet keyboard

In brief: Compact, tenkeyless boards are quite popular among keyboard enthusiasts. There are far fewer choices at the opposite end of the spectrum, however, but one option does stand out from the crowd due to the sheer number of keys it contains.

The Hyper7 R4 from Mechboards is a 173 percent keyboard that was originally designed by Proto[Typist] as a tribute to the classic space-cadet keyboard. It’s absolutely massive, measuring 59.5 x 22 x 6.5 cm (23.42 x 8.66 x 2.5 in), and tips the scales at a hefty 17.6 pounds.

The board features 178 keys laid out in half a dozen separate blocks, including a huge array of programmable keys at the top that are elevated and tilted at a 45-degree angle. It’s offered in your choice of classic or modern layouts and four colors: black, grey, cream, or bare stainless steel.

Tom’s Hardware spent some time with a prototype build of the Hyper7 R4, and provided some insightful feedback to prospective buyers.

The board’s layout is anything but familiar, despite the classic / modern layout choices. Not all of the standard keys are in the location you’re accustomed to, others have unique sizes, and some common keys are missing outright. Translation – it’d going to be difficult to ever get used to the unique layout.

There are also a ton of macro keys with labels that don’t apply to most use cases although fortunately, these can be remapped to better fit your needs.

Pricing is also a major consideration. The Hyper7 R4 starts at $350 but that doesn’t include components like keycaps, switches, or stabilizers, or assembly to put it all together. Enthusiasts may already have switches they want to use but if not, you’ll need to factor that into the overall cost.

If you’re interested in the Hyper7 R4, I’d highly recommend checking out the Tom’s Hardware piece. The board was initially offered as part of a limited run group buy, which has since expired. There are still a few extra units in stock, however, so it’s still possible to get your hands on this unique piece of hardware if you act fast.
