Buying an Intel Atom C2xxx?
Make sure it is a C0 stepping!In January 2017, Intel first publicly acknowledged the issue with flawed
LPCclock outputs on its Atom C2000 system-on-chips. This happened very sneakingly in the form of bug AVR54 in the product specification errata list. This happens to be a very serious issue. It literally is a ticking time bomb under one’s infrastructure. According to the Intel data-sheet,LPC_CLKOUT0andLPC_CLKOUT1are driven by the processor to provide essential timing signals to hardware on the board, including the boot ROM. If this signal stop ticking, the rest of the electronics stops, too.C0 stepping
By the end of April 2017, Intel revealed that its Atom C2000 chip family has a new C0 stepping, up from the previous B0, meaning at least some parts of the chip have been redesigned.
Free Super Micro repair through direct RMA
For EU consumers: The defect existed in the processor contained within the product at the time of manufacture, therefore it was “not of merchantable quality” when acquired. When the failure eventually occurs or whether the product is still under warranty does not matter.

Internal USB 3.0 cable
The case comes with a dual USB 2.0 port at the front. However, the motherboard does not carry an internal USB 2.0 connector. It does feature a 20‑pin USB 3.0 connector. There is also a 9‑pin COM2 connector which, at first sight, might be mistaken for a 9‑pin internal USB 2.0 connector. Luckily, the USB 2.0 cable assembly can be demounted to be replaced by a 20 pin female USB 3.0 internal connector to dual port cable (see picture). Make sure you grab one with the right USB connector separation distance. For the model shown here, I only had to saw off a bit of each lug to make it fit. The original screws and some hot glue keep the connector head in place.
