This R/C Lorry Has a Full Computer Inside

With a monitor, telemetry and an RTX 2060, this drivable remote-control big rig is also a gaming rig

You heard that right: this R/C Mercedes Arocs lorry and trailer combo contains a personal computer that can play Euro Truck Simulator 2.

Matt, aka redditor u/imthatguy77 of US-based Scale Builder's Guild chronicled this impressive build through three videos (above), and the result is a stupendous setup that works both ways: it's still drivable as a remote-controlled lorry and as a liquid-cooled gaming computer complete with Nvidia ray-tracing.

Besides the RTX 2060 KO card from EVGA (who helped make this project possible), the computer runs on an Intel i5 9400F 6-core CPU mounted to an EVGA ITX motherboard along with 16GB of DDR4 RAM, cooled by a 120mm all-in-one radiator cooler setup that's mounted on the back end of the painted and weathered container.

You'd think that cramming this much power on this small a space will pose immense problems, but based on both the above readout and stats provided (only up to 55 degrees Celsius on CPU and 37 on GPU when loaded), it's quite an achievement in design and engineering. Note the component cables running across from the trailer to the cab.

The Mercedes Arocs 1/14 scale model truck itself is slightly more pedestrian by R/C standards, with Spektrum servos, Tamiya MFU and a 55t brushed motor making it move. Because that's the thing. It still is as drivable as a normal R/C big rig.

In a Reddit PM, Matt told me that the biggest challenge he faced throughout the build was in "mounting the components safely and securely" that "definitely ate up the most time," mostly by designing and printing them from scratch. But after ten months (he and Josh, another member of SBG, started the project "back in November of 2020"), they're finally wrapping up and was confident enough to show off the rig on PCMR, where it got over 51,000 ups and massive kudos in over 1000 comments. And why won't he get so much love? It's such a cool machine.

Eventually, Matt continues, he intends to bring this build to EVGA headquarters "as a thanks for working with me on this," en route to plans for an even smaller gaming PC. Considering his last pure PC rig is Gulf McLaren-themed, I'm excited.

Here's the thing though: there is another.

Harley Designs (also affiliated with SBG) also created a 1/14-scale American longhood-style Big Rig Gaming PC based on a Tamiya design and also containing EVGA components. It's equally incredible to behold, though I wonder when we'll see them both together.

  • That is bad ass, I just don't see the point in doing it, but over all, that is sick!

    • With regards PC cases, anything goes. Built one for a friend about 10 years ago inside a WW2 jerry can.
