It turns out a PC desktop tower also makes a pretty good ventilator.

On Wednesday, custom PC vendor Maingear said it was responding to the coronavirus pandemic by building its own ventilators. The result is the Liv, an emergency pulmonary ventilator the company wants supply to hospitals in New York and across the world. 

Maingear is best known for building custom PC desktops and laptops. But now the vendor is proposing to use its manufacturing facilities in New Jersey to churn out the Liv, which it says “can be produced at scale for approximately a quarter of the price of traditional ventilators.”

“It’s one of the advantages of being a small, nimble, and a high-energy business,” Maingear CEO Wallace Santos told PCMag in an email. “We used off-the-shelf parts, including a computer chassis for the working prototype.” He says a single unit will cost around $7,000. 

The machine itself promises to be easy to use, thanks to a touch-screen tablet and preset configurations that untrained users will be able to understand. The same machine is also outfitted with redundant power circuits, safety features, and the ability to drain and collect virus-carrying exhales from the patient’s lungs during the treatment process. 

The Liv was built with the input from a medical advisory board, which Maingear assembled about two weeks ago. As for the ventilator technology itself, Maingear relied on designs currently being used in Italy and Switzerland to respond to the pandemic.

“The Maingear LIV Emergency Pulmonary Ventilator is designed to work safely even in the event that all sensors fail,” the company added. “The device is designed for critically ill and intubated patients (patients undergoing intensive therapy), offering fully automated operation with or without a breath trigger.”

Now the New Jersey-based Maingear is seeking to secure approval from the FDA so that it can begin supplying the ventilators to local hospitals. “Once the production chassis is complete and emergency FDA approval is in place, we’ll be able to produce as many as 200 to 300 units per day,” Wallace added. “Pending FDA approval, we can possibly start production as soon as two weeks from now.”  

In the meantime, the company is trying to build awareness for the ventilator with the hopes of shipping units to hospitals in need worldwide. Interested medical providers can contact Maingear at the dedicated Liv website

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
