Hi    I have a few questions about the Optiplex 9020 SFF. Are all PCIe ports PCIe3.0 or are there any ports limited to PCIe2.0? There are 2 PCIe ports. 1x PCIe x16 and 1x PCIe x4. Can I use both at full speed at the same time? Or is it that when a PCIe3.0 x16 card is used then the 2nd port would be limited to x1 or something like that? About sATA ports. There are 3 of them. Are they all sATAIII (6gbps)? Or is there any port limited to sATAII (3gbps)?   Thank you very much in advance for your help Best, -a-
