That and the fact that it´s not the same size. It won´t fit inside it. It´s too short as Obakasama said.

You can get this adapter: -

As far as I know, you would otherwise have to mod the slot yourself and void your warranty.

I think there's a minor confusion going on (my own included). Graphics cards require the full length PCI-E slot, usually x16 lanes; and depending on the CPU and the physical motherboard could conceivably run at x8 or even x4 for multiple graphics card set ups.
Take for example this motherboard. It has one PCI-E x16 slot and two PCI-E x1 slot. And this has four PCI-E x16 slots (capable of different modes depending on graphics card set ups), one PCI-E x4 slot and one PCI-E x1 slot. On both those motherboards there is a physical difference between x1, x4 and x16 lanes. Note also that a x16 slot has different modes for multiple graphics card set ups.
Then of course there are the different standards of 1.0, 2.0 and 3.0 for PCI-E which increases bandwidth.

This will be pure speculation on my part now.
As I understand it, technically graphics cards rarely run at their full potential as it is. Benchmarks show there is little difference between x16 and x8. Extrapolating those results and referencing them with PCI-E standards I imagine there would be little difference between PCI-E 3.0 x16 and PCI-E 2.0 x16 because of the theoretical maximum amount of data which can be transported with PCI-E 2.0 x16 being very similar to PCI-E 3.0 x8.
I would imagine that a graphics card has a minimum threshold for performance which a particular slot may theoretically provide. Likelihood is a modern graphics card would be bottlenecked by a x1 slot with an adapter simply because the slot wasn't designed to have high bandwidth.
As for the adapter, I think I see where you're going with it but I would imagine it would be difficult. Correct me if I'm wrong, but this is how I'm reading your question. The graphics card at one end can physically fit into the x1 slot (with the rest of the contacts hanging out). The adapter fits into the x1 slot. There's a portion of the graphics card's contacts which are redundant.
I would think the adapter provides physical support; it also provides the correct contacts to the x1 slot because we don't know which contacts are required for data transfer.
Additionally, this thread may be useful for what you have in mind.

Thank you for your input.
I will give it a try. It cannot hurt. The 1X has a data transfer rate of 250MB/s, which is already a lot for desktop use.
Note that the support will not be an issue as the card is also attached to the case.
Bitcoin miners actually use graphic cards in 1x slots using extension adapters, I saw. I suspect that if they hooked up monitors, it would work too.
What I still do not know is why some people say to use an adapter that gets its power externally since the first pins from the 1X correspond to the electric power. What difference could it make?
On this adapter http://i2.cc-inc.com/prod/8081000/8081004_xxlg_2.jpg#, once can clearly see that only 11 pins from the 1X are needed.

Possibly. Personally I would err on the side of caution. Like you suggest, with the screw tightened the graphics card shouldn't sag; I wouldn't take that chance personally having had a graphics card come loose once for no apparent reason...
