TAIPEI—Cooler Master, the day before Computex 2023's official start, opened its new, ultramodern Taiwan headquarters to invited international press and demoed the MasterHUB, a nifty-looking modular peripheral designed for gamers, streamers, and content creators. Building on the signature feature of competitor Corsair/Elgato's Stream Decks—a grid of programmable hotkeys with integrated LCDs on each key—the MasterHUB does it one better. Or, you might say, it could do it several times better, depending on which and how many of its special input modules you install.

Cooler Master’s MasterHub

The MasterHUB comprises a series of modules that can be swapped around and laid out in a huge variety of configurations. At the center of it all is a baseboard peppered with pogo-pin contacts, like so...

MasterHub modules snap magnetically onto the board, and the board, dubbed FlexBase, plugs into your PC via USB-C/Thunderbolt 4 (allowing for DisplayPort over USB connectivity for the screen modules). You can drop on modules for different-size touch screens, knob tri-clusters, or a single scrubbing-type dial with a programmable LCD in the center. Also available will be a thin scroll-bar module, a slider module, and more. In essence, you can assemble an array of modules that suits your specific use case, placed in the positions you find best. Plus, Cooler Master will eventually offer multiple “baseboard” sizes.

How does this translate in practice? A streamer, for example, might want one of the Stream Deck-style button-shortcut modules, along with a fader panel. In contrast, a video editor might prefer the scroll bar and the scrubbing dial. The modules take up different footprints on the baseboard, so you'll need to plan accordingly, depending on the available spaces on the board and what they can fit at one time.

Cooler Master’s MasterHub

Cooler Master intends to offer three different packages of modules and baseboard for three different usage cases: a Streamer Kit, a Video Editor Kit, and a Photo Editor Kit.  These packages include modules that the company deems an appropriate mix of MasterHUB modules for the specific user profile. (The Streamer Kit, for example, includes the base, the 15-key button panel, the five-slider module, and the scroll wheels strip.) Additional modules will be sold, meanwhile, direct from Cooler Master, in the event a buyer wants one of the modules that's outside the pre-baked bundle they get.

Especially striking is the three-by-five button panel, which has individual IPS screens on each key; you can customize the key images to help you remember which key does what. Different programs will require patches or plugins installed to the MasterHUB to allow you to create shortcuts and program functions to the key, slider, dial, or other control in question. And there, of course, will be the make-or-break for the MasterHUB: how well it plays with key software packages, and how easy it is to program commands.

The company also demonstrated a new software control scheme that will govern MasterHUB. Much more than just a face for MasterHUB alone, the new MasterControl is partly system-monitoring software, partly a control UI for all Cooler Master hardware you may have in your PC.

The user interface looks clean, and is segmented logically according to theme and product type. Looking at competitor “ecosystem” UIs such as Razer Synapse or Corsair’s iCUE, given how many categories of gear Cooler Master has in the market, it only makes sense for the UI to be unified across the hardware.

Cooler Master’s MasterHub

We got a brief look at the nuts and bolts of MasterControl, and came away guardedly optimistic. This new software will eventually take the place, as well, of existing Cooler Master control schemes, and a new sign-on account (the Master ID) will tie together your settings, the record of Cooler Master gear you own, and the ability to move your accumulated data to a new system.

Expect the MasterHUB bundles to launch near the end of this year. Pricing was not yet announced.

My Experience

I have been a technology journalist for almost 30 years and have covered just about every kind of computer gear—from the 386SX to 64-core processors—in my long tenure as an editor, a writer, and an advice columnist. For almost a quarter-century, I worked on the seminal, gigantic Computer Shopper magazine (and later, its digital counterpart), aka the phone book for PC buyers, and the nemesis of every postal delivery person. I was Computer Shopper's editor in chief for its final nine years, after which much of its digital content was folded into PCMag.com. I also served, briefly, as the editor in chief of the well-known hard-core tech site Tom's Hardware.

During that time, I've built and torn down enough desktop PCs to equip a city block's worth of internet cafes. Under race conditions, I've built PCs from bare-board to bootup in under 5 minutes. I never met a screwdriver I didn't like.

I was also a copy chief and a fact checker early in my career. (Editing and polishing technical content to make it palatable for consumer audiences is my forte.) I also worked as an editor of scholarly science books, and as an editor of "Dummies"-style computer guidebooks for Brady Books (now, BradyGames). I'm a lifetime New Yorker, a graduate of New York University's journalism program, and a member of Phi Beta Kappa.

The Technology I Use

I use a lot of computers on rotation in my daily work, but I rely on just a few to get things done. I split my work life mostly between a Microsoft Surface Laptop 3 (a 15-inch Ryzen model), paired with a Lenovo ThinkVision portable monitor, and a custom-built big-chassis Windows 10 desktop PC that has served me well for years now. (Specs: Liquid-cooled Intel Core i7-6950X Extreme Edition, 32GB of RAM, and a GeForce GTX 1080 card.) That's all in a giant chassis with six hard drives and SSDs packing its bays. (As I upgrade systems, I just keep moving the old warhorse drives over.) This behemoth is hooked up to a 32-inch LG monitor.

I also have a bunch of PCs around the house, all custom builds: another one attached to my main TV (for gaming and occasional forays into VR), a mini-PC on the bedroom TV (acting as a media server), and a Mini-ITX desktop in a corner of the living room...just because. I carry around an oversize OnePlus phone, but when I do long-haul travel, a vintage iPod Touch comes along, too, for old times' sake.

I wasn't always a PC guy. I cut my teeth on a cassette-drive-equipped Commodore VIC-20 in the 1980s. But I got serious with Apple desktops in the early 1990s, starting with a Macintosh SE, then a Macintosh LC, and finally one of the short-lived Umax "clone" Macs, before building my first PC and never looking back.

With all my typing and editing work over the years, I've become a huge proponent of thumb trackballs, which minimize wrist action (and my wrist pain). I have a secret cache of the long-discontinued Microsoft Trackball Optical Mouse (my personal favorite), held in an undisclosed location.
