The Crosshair X870E Edition 20 goes beyond an anniversary finish. ASUS pairs it with a Ryujin 360 designed to cool the processor and power stages, plus two huge screens. Everything arrives in a reusable ROG suitcase. At over €3,000, this bundle clearly targets enthusiasts seeking something exceptional. We installed and used it in our Edition 20 PC.
A suitcase for a motherboard
This is the biggest and most luxurious motherboard packaging we have seen. The carton is even larger than the GR20 case’s box, with 24 kg marked on the package. That refers to the complete package, not the motherboard alone.
Inside, the motherboard and cooler sit in a ROG-branded cabin-size suitcase. The protection reminded us of a Pelican Case: every part is securely held and protected. The suitcase can be reused afterwards. For a collector’s edition, that detail really stood out.
Our partner Absolute PC purchased this bundle. During our test, it cost around €3,200, or €3,100 at Absolute PC.
A massive, carefully finished motherboard
The Crosshair X870E Edition 20 feels heavy and massive in the hand. Its finish seemed on a par with a ROG Crosshair X870E Glacial: this is clearly at the very high end.
ASUS lists a 24 + 2 + 2 power-stage design and five onboard M.2 slots, two supporting PCIe 5.0. With the intended expansion options, M.2 support can reach nine drives [1]. We installed just one 4 TB Samsung 9100 PRO.
Installing the processor, memory and SSD was straightforward. Access and mounting mechanisms felt practical, as we expect from ASUS boards in this class.
Our only regret was having to remove the decorative PCIe slot covers to fit the graphics card. They serve the board’s presentation out of the box and cannot go back in our build. In practice, this barely shows: the Astral RTX 5090 Edition 20 is so large that it hides the area.
A Ryujin designed for this bundle
This Ryujin 360 is one of the bundle’s most interesting features. Its huge block covers both the CPU and the motherboard’s power stages. ASUS confirms a high-purity copper cold plate designed for this shared cooling role [1].
ASUS lists an Asetek EMMA Gen10 V3RX pump and a 40 mm-thick radiator [2]. This is not merely a regular Ryujin in another colour. Its integration also explains why we cover the motherboard and AIO in one article.
Installation in the GR20
Mounting the block, tightening it and connecting everything seemed easy. We replaced the original thermal paste with Thermal Grizzly Kryonaut Extreme. That choice is part of our measurement conditions.
In the GR20, the radiator sat on the right at the rear. We had attached the block to the motherboard before finishing installation, so a second person briefly held the radiator during screwing. Tube routing was easy but required opening the top of the case.
Two impressive screens
Once the PC is on, the screens’ size is the most striking feature. ASUS lists two 6.67-inch AMOLED panels [2]. In person, they look spectacular. Brightness suited us perfectly, and the matte surfaces caused no distracting reflections during use.
We kept the original synchronised display in ASUS InfoHub Edition 20, together with the Astral graphics card. The software recognised the hardware and worked immediately, remaining trouble-free through restarts and games. For software of this kind, that simplicity deserves credit.
We also physically pivoted the Ryujin assembly left and right without changing orientation in the software. The screens were mainly visual attractions for us, but they add greatly to the enjoyment of this build.
First boot and settings
The first boot went smoothly. We then installed BIOS 1002 and adjusted the memory. The 48 GB CUDIMM kit, comprising two 24 GB modules rated at 9,200 MT/s, was deliberately set to 8,000 MT/s as a precaution for long-term stability. This was not a limit encountered while searching for the maximum speed.
Apart from memory, we did not change BIOS settings. We used Ethernet. Wi-Fi, Bluetooth and other connectivity features are not evaluated in this article.
Measurement conditions
Measurements used the Ryzen 9 9950X3D2, the ROG Astral GeForce RTX 5090 Edition 20 with NVIDIA driver 616.92 and the ROG Thor 3000W Titanium III Edition 20 PSU. The GR20 stood vertically with its cross-flow fan running. The graphics card retained stock settings.
The records specify 21 °C ambient temperature for all four tests. The Ryujin fans followed a progressive automatic curve. Speeds in the table are observed operating speeds, not identical fixed targets for each workload.
The whole PC sounded very quiet during our use. We did not measure pump and fan noise separately.
OCCT Stability Test ran for 60 minutes with the Large data set, Extreme mode and variable load. Instruction set and thread settings were on Auto.
Recorded temperatures
Each scenario consists of one run. For Cinebench, the average temperature covers the final ten minutes.

Fans
In Cinebench 2026, the sheet records a 69 °C average and an 82 °C maximum at 228 W average CPU power. OCCT gives 71 °C and 84 °C. The gaming reading is lower, averaging 60 °C with a 75 °C peak.
These temperatures seemed respectable in our build with automatic Ryujin fan control. We did not test another cooler under identical conditions or measure VRM temperatures.
Key takeaways
This bundle is a collector’s piece from the moment you unbox it. The reusable suitcase, massive motherboard and huge screens make it particularly enjoyable to discover. Assembly remains manageable, and InfoHub gave us a trouble-free experience.
At €3,100–3,200, exclusivity is what mainly explains the price to us. The measured performance alone is not enough reason to spend this much on a motherboard and cooler.
Our main regret concerns the Ryujin: we would have liked to buy it separately. Its design around this board’s CPU and VRMs makes that less straightforward than it sounds. We hope a future, more broadly compatible Ryujin gets an equally generous screen. Not much bigger, though, or the PG27 Edition 20 might lose customers!
