Those are PCI-E risers and not GPU's 
Depends heavily on which flavour you're mining.

*facepalm* stupid me thought the cables were for power only, but they work as riser cables then, right? I only know the x16 ones

Does this use something like a PLX chip for extra lanes?

It shouldn't need to they are all 1x.
Most likely not.
12 GPUs with 1 lane each would be only 12 PCI-e lanes.
So less than one full GPU would use.
It's hard to say. In 2013 every thing came crashing down after a few months when the Block Chain Equations were broken and ASICs were developed to do the job.
Word on the street is Ethereum is "ASIC Resistant" if this turns out to be the case the current craze could be with us for a while.

Yeah you can get away with 1x speeds, because you don't need to move that many data, you are just doing computations. Those two molex plugs though are going to be essential to the motherboard

Surely this limits the bandwidth and performance?

It does, but quantity over quality for mining.

But.... How does cutting down the bandwidth even help? You're limiting the performance so significantly I don't think 12 GPUs are going to help overcome the defecit? I didn't calculate it anyway so probably wrong.

They don't have much choice. More the merrier, and of course you can't run GPUs like that any way so they usually just used a 1x converter any way. It's like a small PCB, then a USB3 cable, then another small PCB goes onto the GPU.
At least now people won't get conned buying ex mining GPUs that blow up after a week.

Well I guess I'll just have to accept your answer. I have no clue how it works lol
But yes finally a little bit more protection. I remember after the R9 200 series cards were bought up in buckets and the whole craze started dying down the second hand market was flooded with essentially destroyed 290/290x cards. So little more protection but honestly it's really just a buffer and delays the inevitable. After the mining cards are sold out they will turn to consumer cards and those will still sell out.
