This is a rough illustration of how the GPU and motherboard are going to be positioned in my custom case.
2547355


GPU: ASUS GTX970 Mini, Motherboard: Gigabyte Z97N Mini ITX (for now)

What extender cable should I get?

I only know that people have tested pcie2 cables and found no notiecable difference in benchmarks between no extender, expensive extender and cheap extender from ebay. However, found no rel info for PCIE3.
Also which cable will suit this setup best (minimum length, type) and which ebay seller do you know which actually makes PCIE3 extenders and doesn't just claim it is.

Is there any electrical difference between a PCIe 2.0 extender and a PCIe 3.0 extender? I assumed that the actual slot and connector was identical.

Also, your layout looks quite similar to something like the Silverstone ML07- mini-ITX board, GPU on a riser. Maybe you would be best off getting hold of one of these as a basis, and customising the case from there?

Yes, there are differences, 8 GHz instead of 5 GHz. I'm not a professional in that field but it's likely to be more sensitive to interference, and maybe something else.

No, sadly. All the parts of the device except the first "floor" which holds the mothertboard and GPU (among other things not shown) have been hidden in that simplified illustration.
