Versatile 8-litre barebone

The ASRock DeskMeet X300 is an 8-litre mini-PC barebone that accepts AMD Ryzen AM4 desktop processors up to 65 W. It targets builders who want a compact system for daily computing, gaming, home entertainment or content creation without committing to a proprietary form factor. The chassis can stand vertically or horizontally to suit desk space.

Build integration and expansion

The board provides a PCIe 3.0 x16 slot for a dual-slot graphics card up to 20 cm long, freeing users from integrated graphics limits. Four 288-pin DDR4 DIMM slots support up to 128 GB in dual-channel mode at 3200 MHz with Ryzen 5000 or 4000 G-Series, or 2933 MHz with 3000 and 2000 series. Storage options include two SATA 6.0 Gb/s ports and one Ultra M.2 2280 PCIe Gen3 x4 slot. CPU cooler height is limited to 54 mm.

Bundled connectivity and software impact

Front I/O supplies one USB 3.2 Gen1 Type-C, two USB 3.2 Gen1 Type-A and two USB 2.0 Type-A ports for peripherals. Rear video outputs comprise DisplayPort, HDMI and D-Sub, enabling multi-monitor setups without a discrete card. Onboard Realtek ALC897 audio and RTL8111H 1 Gbps LAN handle sound and wired networking. A key-E 2230 M.2 slot is reserved for a Wi-Fi and Bluetooth module, which is not included.

Questions about this item

Will a 65 W Ryzen 5000 CPU hit its thermal limit with the 54 mm cooler height restriction?

The chassis only accepts CPU coolers up to 54 mm tall, matching the AMD Wraith Stealth, so a 65 W processor stays within its designed cooling envelope.

How loud and hot does the system get when a dual-slot graphics card runs all day in the 8-litre case?

A dedicated MOSFET heatsink handles VRM heat, while the single PCIe 3.0 x16 slot vents through the side panel, keeping sustained GPU loads manageable in the compact volume.

Which DDR4 DIMMs must I already own to reach 3200 MHz on a Ryzen 5000 G-Series chip?

Four 288-pin DDR4 modules rated for 3200 MHz are required; the board runs Ryzen 3000 or 2000 series at 2933 MHz instead.
