The visual difference is:
Rev. 1.0 only has a 4-pin ATX12V connector for the CPU.
Rev. 1.1 has an 8-pin ATX12V connector for the CPU.
Regarding the two network controller are based on an Atheros.
Rev 1.0 Atheros AR8151 and Rev. 1.1 may be an AR8161. But I have not been able to verify the manufacturer's website.
If not for the rest of the package is complete 4 sata cable.
And thank you to Amazon for quickly ordered and delivered quickly
