Hi. I bought a Thinkcentre M910s (Intel Core i7-7700) and would like to add an external graphics card. Which would be suitable for this case and motherboard?
Slot 1: Low Profile, PCIe 3.0 x16
Slot 2: Low Profile, PCIe 3.0 x1
Slot 3: Low Profile, PCIe 3.0 x16 (x4 signal)
Some: 210 watts, autosensing, 85% PSU

Lenovo has "shortened" the case used for the M910s SFF which severely affects the maximum length of any graphics card you might want to install. The PSREF states that PCIe x16 cards must be < 150mm.
So the possible options for adding external low-profile decently performing graphics cards which will actually fit is very limited. Unfortunate, but true.
However this sticky thread suggests the nVidia low-profile GT1030 and makes the case for why this is your best option given the size constraints of this SFF case.

I understand, thank you very much.
Will it be recommended to put the motherboard of the m910s in a new enclosure by adding a new source and then a new graphics card?

If you had bought the M910t tower instead of the SFF version, the tower case is bigger than the SFF case. Then you could have then gone with a nice graphics card upgrade like the nVidia EVGA GTX 1050ti which is a full-size card with a single-fan design (so that it is shorter than a two-fan card). So physically this is an ideal card with very good performance to use in this tower case
Furthermore the M910t tower comes with a somewhat larger power supply. But the other nice thing about 1050ti card is that it is a low-power GPU which mean 75W TDP, in other words you don't have to upgrade the standard PSU in the M910t in order to use the 1050ti. It doesn't require any additional power other than what is available on the PCIe bus, which is good because the stock PSU doesn't have any PCIe power cable additionally required for a really high-end graphics card that needs more than 75W.
