The short version

Key points

  • The system uses an AMD Ryzen 7 5825U processor and can be configured with 32GB of RAM and a 1TB SSD.
  • Its key feature is a concealed compartment containing four 3.5-inch hard-drive bays.
  • The system can run Windows, Linux, Docker or TrueNAS rather than being limited to proprietary NAS software.
  • Connectivity includes two 2.5GbE ports, USB-C, DisplayPort, HDMI, four USB-A ports, a 3.5mm audio jack and a TF card slot.
  • The included 120W power brick is relatively compact, but the internal fan is louder than Pat expected and may be worth replacing with a Noctua fan.

A mini PC with a four-bay secret

The AOOSTAR WTR Pro looks like a conventional, relatively thick mini PC, but a removable section hides four 3.5-inch hard-drive slots. This changes its intended use significantly: it can operate as a compact storage server or NAS while retaining the flexibility of a normal computer.

The review unit included a Ryzen 7 5825U, 32GB of RAM and a 1TB SSD. A barebones configuration is also available, so buyers do not necessarily have to use the supplied memory and storage options. The configuration discussed in the video was priced at about $920 Australian.

More flexible than a conventional NAS

Unlike many traditional NAS products, the WTR Pro is not tied to one manufacturer's operating system. It can run Windows or Linux, with the possibility of using Docker, and Pat specifically mentions installing TrueNAS as an option.

The hardware also includes two notebook-style RAM slots and three M.2 slots. These can be used to expand storage, while one M.2 slot could potentially be used for a Wi-Fi card. This gives the system more upgrade and software flexibility than the proprietary NAS ecosystems Pat compares it with.

Connectivity and everyday uses

The WTR Pro has two 2.5GbE Ethernet ports, which are intended to support faster data transfers across a suitable network. Other connections include USB-C with display and power functions, DisplayPort, HDMI, four USB ports - two USB 3 and two USB 2 - a 3.5mm audio jack and a TF card slot.

Pat identifies several possible uses, including a Plex server, a video storage system and a general-purpose computer with substantial local storage. The Ryzen 7 processor and integrated AMD Radeon graphics are suitable for high-resolution desktop use, including 4K at 60Hz, although gaming is not the focus of this device.

Cooling, noise and design

The chassis is made from thick metal, which helps with heat dissipation. Air is drawn in through one area and exhausted from the rear. During testing with four 3.5-inch hard drives installed, Pat did not encounter overheating warnings or a drop in performance, although the system became warm.

The main criticism concerns the fan. Pat found it louder than expected, partly because it is not a name-brand unit, and suggested replacing it with a Noctua fan. The system is designed to be accessible, with the RAM and M.2 slots available from the bottom without removing the entire outer shroud.

The power supply is a 120W brick, described as small for a system of this type. The power button is positioned behind the sliding WTR Pro logo, while the side-mounted I/O contributes to the unit's distinctive design.

TechManPat’s conclusion

I think the AOOSTAR WTR Pro is most appealing as a flexible, compact NAS platform rather than as a gaming PC. In my view, the four drive bays, expandable internal hardware and ability to choose the operating system make its chassis valuable, although the fan noise and price of about $920 Australian should be considered before buying.
