Huawei is now said to be about to mimic Apple in launching a PC with its own in-house ARM CPU. However, this putative desktop can also apparently support DDR4-2400 RAM, M.2 SSDs and PCIe 3.0 expansion. These internals may be housed in a relatively slim tower-form case, and may be paired with the OEM's also-rumored first-gen monitor.
