Hello 
I recently purchased a ThinkCentre M80s Gen 3
11TL0006UK computer and i am very happy with it. I just can't understand one thing. When I open the computer, there was only one rail for the m2 SSD. I mean the plastic that holds the m2 SSD. There is no way to attach a second m2 ssd. Why is this not in the box? 
I've looked all over the internet and can't buy it anywhere. It is impossible to buy. It is big problem because in this situation, I can't install the second m2 ssd ? How to mount a second m2 ssd in this situation? Lenovo you should put the second bracket inside the computer. What I should do now ? Can you help?

Welcome to Lenovo Community tiesto1820,

After reviewing the specification sheet for the ThinkCentre M80s Gen 3, we have found that the computer only includes one M.2 SSD bracket pre-installed, and there is no additional M.2 slot available for direct installation onto the motherboard. This is why you are unable to attach a second M.2 SSD to your system.

However, there is still a solution available to you. You may consider purchasing a third-party M.2 SSD bracket that is compatible with your computer. We advise caution if you decide to open your computer to install the second M.2 SSD without a proper bracket, as this may cause damage to your computer's components.

We apologize for any inconvenience this may have caused you, and we understand the frustration of not being able to install a second M.2 SSD. In case you need additional storage space, you can use an external SSD through a USB port or add a traditional 2.5-inch SSD or HDD to the system.

We hope that this information helps you find a suitable solution to your problem.

I've recently had complete success adding another M.2 to my desktop (mine's a 920S, but the same principles apply to yours) with an adapter bracket for one of the PCIe slots. Here's some info on what I found that works beautifully on my machine:

M.2 PCIe NVMe 4.0/3.0 Adapter with M.2 Heatsink for M.2 PCIe SSD (NVMe and AHCI), PCIE X 4 Full Speed, Desktop PC Installation

This can be found at (I'm in Canada, but you can find these in your country, I'm sure)

Hi

Please show me where in this document what you sent ...specification sheet for the Thinkcentre M80 Gen3....it says that there is only one m2 ssd bracket in the computer and i wont be able to install a second ssd m2 disk if I buy it ? You wrote that you found it in this document Can you show me where it is because i dont see it and i believe you are lying.

THERE IS additional m2 slot available for direct installation onto the motherboard but there is no bracket for it !

I dont understand how you can sell someone a computer with additional ssd m2 slot available but without the possibility of installing it in the computer because there is no bracket for it !

I dont understand how you could not add this plastic where you can instal secound disk ?

It is like buying a cheese sandwitch at the store and not getting cheese on the sandwich !

Stupid plastic which is not expensive at all but you cant buy it on the entire internet ! You cant buy this anywhere EVEN ON YOUR OFFICIAL LENOWO WEBSITE !!!

It is absolutely disqusting !!! I bought a second ssd m2 2 tb and i cant mount it !!!

Maybe you can show me the exact place in the uk where i can buy it ? Exact place where THIS PART IS AVAILABLE FOR PURCHASE ! Please....show me ?

I checked this probably 20 times but what for if I cant buy this from your website anyway ? I dont understand why youre showing this to me ? I am supposed to look at this ?

I wrote you earlier:

Please show me exact place where THIS PART IS AVAILABLE FOR PURCHASE ! Show me a place where i can buy this ! Youre showing me some photos. I can show you 100 photos too but what for if Ive been looking for this all over internet and i cant buy this anywhere !

This part should be inside the computer which I bought ! You didint put this in there!

Now, I bought a second ssd m2 2tb and i cant mount it because there is no bracket for ssd m2 in the computer that SHOULD BE THERE !!! This part is missing! It is absolutely disqusting!

I will say again:

Please show me place where THIS PART IS AVAILABLE FOR PURCHASE! Show me a place where i can buy it. Please.

Based on the information in this thread, and the part description, this part is only for the Tower (13.6L is the volume of the tower case) and not for the SFF.  The SFF uses two of the regular bracket, which should have better availability than a specialized bracket.
