Who it fits
Good fit for
This mini PC suits builders who want high raw performance without paying for pre-installed Windows licenses or fixed RAM configurations. The OCuLink port makes it ideal for users planning to add an external GPU for serious gaming or creative workloads. The dual storage bays and high RAM capacity appeal to content creators managing large video files. It also fits users who need quad-display support via DP 2.1 and HDMI 2.1 ports for multi-monitor setups.
Who should skip it
You should look elsewhere if you need a ready-to-use computer out of the box. This barebone unit requires you to purchase and install your own RAM, SSD, and operating system. If you are not comfortable with hardware assembly, this model may be too complex. Additionally, the OCuLink port requires one M.2 SSD slot, which reduces your total storage options if you plan to use both slots for drives. It is not suitable for users who want a plug-and-play experience.
Verdict: The Reatan Ryzen 7 255 Oculink Mini PC offers a powerful, flexible foundation for custom builds. It is best for experienced users who want to maximize performance through external GPUs and ample storage expansion.

This minimalist approach suits users who prefer clean and tidy workspaces. The sturdy build protects internal components from accidental bumps. You can trust the chassis to keep everything safe and secure. This design prioritizes function without sacrificing visual appeal for your space.
Setup and Everyday Use Guide
This unit arrives as a barebone system, meaning you must supply your own components before it can function. You need to install RAM and storage yourself. The chassis includes two SODIMM slots that support up to 96GB of memory. You also have two M.2 2280 PCIe slots for storage. These slots accept PCIe 3.0, PCIe 4.0, or SATA drives. You can install two SSDs simultaneously, with each drive holding up to 2TB for a total capacity of 4TB. You must keep in mind that the OCuLink port requires one of these M.2 slots and does not support hot-swapping.
For display connections, you have one DisplayPort 2.1 and one HDMI 2.1 port. Both support 8K resolution at 60Hz. You can also use two USB4 ports to drive a quad-display setup. This allows you to connect multiple monitors for productivity or media playback. The device includes a 2.5GbE LAN port for stable wired networking. Wireless connectivity is provided by Wi-Fi 7, which offers faster speeds and lower latency than previous standards.
Daily operation involves switching between three modes. You can choose Silent Mode for quiet environments, Standard Mode for balanced use, or Performance Mode to unlock maximum hardware potential. The all-metal chassis features dual side metal grilles. Dedicated cooling fans for memory and SSDs help maintain stable performance during high-load tasks. You also get a built-in dual microphone and speaker for basic audio needs.
What You Need To Buy
You must supply your own RAM and storage before this unit functions. The chassis includes two SODIMM slots supporting up to 96GB of memory. You also need to install two M.2 2280 SSDs, which can reach a total capacity of 4TB. Check that your chosen drives are compatible with PCIe 3.0, 4.0, or SATA standards. Since the system lacks an operating system, you will need to create bootable installation media and install Windows or Linux yourself. If you plan to use the OCuLink port for an external graphics card, remember it occupies one M.2 slot and does not support hot-swapping. This setup suits users who want to customize their hardware. It fits well alongside other barebone options for those who prefer building their own systems rather than buying pre-configured units.
Check before you buy
- Purchase compatible DDR5 SODIMM RAM up to 96GB total capacity.
- Buy two M.2 2280 SSDs supporting PCIe or SATA interfaces.
- Prepare Windows or Linux installation media for initial setup.
- Ensure your power supply meets PD requirements if using USB4.
