You can't get an ARM one though, only X86, which is mostly the point.
True. However, I've always noticed that ARM has less Linux support than x86, and the main benefits ARM is known for are typically performance/watt, running cooler, and less legacy support. Since this server seems to have pretty average performance/watt and cooling, I can't really see much advantage to ARM here, at least for typical server use cases. Unless you're doing ARM development, but I feel like a Pi 4/5 is bet…
This computer uses 8 Cortex-A720 cores (and 4 little cores with negligible performance), which have a performance similar to the older Intel E-cores, i.e. Gracemont or Crestmont from Alder Lake, Raptor Lake or Meteor Lake. They are much slower than the recent Intel E-cores, i.e. Skymont or Darkmont, from Arrow Lake or Panther Lake.
So the performance of the whole CPU is similar to the 8-core Intel N300 (Alder Lake N) or Intel N350 (Twin Lake), which are found in various mini-PCs that are cheaper than this ARM computer.
Even so, the performance of this ARM CPU is many times greater than that of a Raspberry Pi and greater than of any cheaper ARM CPU. For greater performance, you must buy a more expensive smartphone, or a Qualcomm or Apple laptop or mini-PC, or a very expensive development computer from NVIDIA.
