This handheld gaming PC is made of an ASRock 4X4 mini PC board with Ryzen 7 4800U

There are a growing number of options for people looking for a handheld gaming computer. But why buy a Steam Deck, AYA Neo, GPD Win or AYN Loki when you can make your own?

Redditor SerMumble decided to go the latter route with a DIY Cyberdeck meant for gaming on the go. It combines a motherboard meant for mini PCs with a 9-inch screen, detachable game controllers, batteries and a 3D-printed case, among other components.

The heart of the operation is the ASRock 4×4-4800 motherboard, which is a 4.09″ x 4.02″ board with an AMD Ryen 7 4800U 8-core, 16-thread processor with Radeon Vega 7 graphics. While the motherboard is designed for compact desktop computers, the processor is designed for laptops and is therefore energy efficient enough for a battery-powered computer.

SerMumble notes that the system is powered by a custom battery pack with four to eight 18650 Lithium Ion batteries and gets anywhere from 1 to 5.5 hours of battery life, depending on usage (some games run best with the processor’s TDP set to 35 watts, while others run fine of 10-15 watts).

In addition to the motherboard and battery, the handheld DIY features a 9-inch IPS LCD touchscreen, a thumbpad grafted onto the system, and a third-party Nintendo Switch wireless controller that attaches to the sides of the device.

The system has 32GB of RAM and like 1TB SSD, but these specs should be customizable, as the ASRock board has two 260-pin SODIMM slots with support for up to 64GB of DDR4-3200 memory and M.2 slots for storage and /or wireless contacts.

You should also be able to add a variety of accessories, as the board also has plus many ports, including:

  • 1 x HDMI 2.0a
  • 1 x DisplayPort 1.2a
  • 2 x USB 3.2 Gen 2 Type-C
  • 2 x USB 3.2 Gen 2 Type-A
  • 2 x USB 2.0 Type-A
  • 1 x 2.5 GbE Ethernet
  • 1 x Gigabit Ethernet

ASRock also offers similar cards with Ryzen 5000U series processors or Intel chips, so the design is theoretically quite versatile.
