Minisforum has presented or at least teased the UM890 WE, a somewhat larger mini PC. Exact specifications, including the size, are not yet available, but the width of the housing is likely to be less than 20 cm, while the height is likely to be significantly greater.
In terms of actual dimensions, a graphics card could certainly fit into the housing, but Minisforum has decided against this for the UM890 WE. Instead, the manufacturer utilizes the space for an integrated water cooling system intended to cool the installed AMD Ryzen 9 8945HS adequately, even under heavy workloads. The AMD Ryzen 9 8945HS is a high-end notebook processor/APU based on Zen 4 architecture. The 8 cores can process 16 threads, and individual cores can clock up to 5.2 GHz. It is quite likely that the AMD Ryzen 9 8945HS in the UM890 WE will not have any thermal limitations.
There are two USB-A ports on the front of the PC case, plus a USB-C port. Two USB 4 ports are advertised, which can also be used to connect monitors. Dedicated graphics cards can be used in the form of external GPUs, for which a fast OCuLink port is available. Lastly, two RJ45 ports with a maximum data transfer rate of 2.5 GBit/s each are on board.
There is currently no information on price or availability, but the powerful mini PC is unlikely to be cheap.
