Re: New M910s SFF just arrived: M.2 and graphics hardware surprises/problems

So the M910s SFF case is a full 3" narrower, meaning that when the swing-up drive bay assembly is closed its "leading edge" intrudes 3" further over the motherboard than it used to.  And that means there is now 3" less clearance for the ends of expansion cards inserted into expansion slots on the motherboard.  ...

 

But this newest SFF case is only about 11.5" wide, not 14.5" wide.  So a full 3" of internal clearance needed for expansion cards has been eliminated.  Whereas 14.5" outer dimension allows pretty much ANY low-profile graphics or PCIe expansion card to be used (assuming adding one was part of your purchase plans), the new 11.5" outer dimension now limits expansion cards to be about 5.75" or smaller.)

 


To clarify for others, since I was initially confused.   When DSperber writes about narrow and wide, it's not about the side-to-side, but front-to-back.   The PCI cards install with the end plate (and in the case of graphics cards, the video ports) on rear of the system.   So the length of the card is the distance from the rear to the front of the system.   (Note that the power supply is moved to the left side, which will make the system more stable when placed upright.)

 

Kudos to DSperber for documenting the change in the size of the case, and issues with upgrading to a decent graphics card with the new SFF.   In my mind, it narrows the gap between the new M710 & M910 Tiny model and the new SFF, since the M910 Tiny now supports two M.2 storage cards and one SATA drive. 

 

Edit:  recent reports show the M710 Tiny with one M.2 storage card slot.  Edit 2:  Only the M910x Tiny has two M.2 storage card slots.

Re: New M910s SFF just arrived: M.2 and graphics hardware surprises/problems

2017-07-21, 3:12 AM

Just a bit of a post-script on this story...

 

The original M910s SFF was returned for refund, and a new M910t "tower" was ordered and has now arrived (along with the M.2 SSD kit so that I could install a Samsung M.2 960 EVO drive. I have to say that I did expect a significantly larger "tower" case than the much-reduced-in-depth SFF case, but this was not so much how it turned out. Turns out Lenovo has also significantly reduced the "depth" dimension  (i.e. the large side edge which runs from the front face to rear of the case) of the tower!

 

The new M910t tower case is 6.5" wide, by 16.2" high, by only 12.7" deep.  This is in contrast with the M910s SFF case which (when standing up vertically) is 3.6" wide, by 13.5" high, by 11.4" deep.  That means the "tower" case is actually only 1.3" deeper than the SFF case, although it is also thankfully about 3" wider.

 

What this means is that the swing-up/down drive bay assembly is now safely about an inch  above the top edge of the full-size EVGA GTX 1050ti graphics card I am now able to successfully install.  The full-size card itself is actually a relatively short 5.7" long, so its length would not have been a problem even in the SFF case (where only about 5.75" max card length would fit).  But as a full-size card it's 4.4" tall which thanks to the 6.5" width of the tower case keeps it safely under the edge of the fully closed swing-down drive bay assembly.

 

So, no more physical problems with installing the M.2 card and add-on graphics card.  But if you had any expectation of being able to do just about anything else inside this "tiny tower", a reality check is mandatory.  You will find this is not anything like the true mini-tower cases Lenovo used to provide.  For comparison:

 

M910t - 6.5" W x 16.2" H x 12.7" D

M93p - 6.9" W x 16.3" H x 17.4" D

M92p - 6.9" W x 16.3" H x 17.4" D

M900 - 6.9" W x 16.1" H x 16.3" D

Re: New M910s SFF just arrived: M.2 and graphics hardware surprises/problems

One more thing to mention which surprised me about the M910t...

 

I ordered it with an optical CD/DVD drive.  I expected it to be a conventional "thick profile" drive, aligned in a horizontal 5.25" bay. But that's now what came.

 

Instead, the ultra-slim profile drive is what Lenovo has used, aligned vertically on the left edge (looking at the face), same as it is in the SFF case.  And that also means there is a vertically aligned "available internal 5 1/4" bay space" to the right of the optical drive.  I don't know what you might install there, as there is a second 2.5" drive bay attached to the back of the primary 3.5" HDD drive bay.  And there is no removable front bay cover, so whatever you install it would have to be a fully internal device.  Perhaps if I'd ordered an SD card reader it might have gone into this open drive bay space and they would have used a different front bay cover to expose the card reader slots.

 

Anyway, in total, this is really a "tiny tower".  It can actually be turned on its side on a tabletop instead of stood up vertically, and still will not take up much more tabletop footprint than the SFF case would have used.  So using it as a sideways tabletop base on top of which a monitor could be placed, the monitor will simply end up being about 2" higher to your eyes than had it been placed on top of a SFF case also laid sideways on the table.  You don't have to use this "tower" vertically only.  Interesting.

Re: Lenovo ThinkCentre: Nvidia GT 1030 graphics card officially supported (best low-power, 4K video

2018-07-29, 21:48 PM

Hi all,

I have a M910t provided by my company for home office. Do you think I can add a 1050 Ti LP on the 250W PSU ? On all salers website the specifications are a 300W PSU but it is for the complete computer, I don't know only for the graphic card.

Absolutely no problem.  And no need for low-profile either.  Full-size card fits just fine in the tower case.

 

I built a 910t for a friend and installed a full-size EVGA GTX 1050ti SC (75W TDP and single-fan design, so it's short), and it works perfectly with the stock PSU (which supports up to 75W graphics card on the PCIe bus alone).

Thank you so much for this quick answer, i don't know if i will buy this board or waiting for a LP in the new generation.

Re: New M910s SFF: M.2 and graphics surprises/problems (SOLVED: M910t with GTX 1050 installed)

2018-11-22, 19:01 PM

Thanks for the info. I was panning to buy a M920 SFF but it seems it has the same dimension as M910s. It means that there is no way to install a GTX 1050ti inside the chasis. However, I found another model P330 SFF with 260W power supply and the following dimensions:

 

Height: 343.5 mm (13.5 in). Width: 92.5 mm (3.6 in). Depth: 305.6 mm (12 in)

 

As I can see, this model is 0.6 inch longer than M920 SFF in terms of depth. Do you think it is possible to fit Zotac GTX 1050ti low profile(160MM length) mentioned in your later post? By the way, I think the spec in the document for Expansion slots which claims to support full height card is wrong.

Re: New M910s SFF: M.2 and graphics surprises/problems (SOLVED: M910t with GTX 1050 installed)

I honestly don't know the answer to your question from firsthand experience.

 

But the PSREF for the P330 SFF shows the PCIe x16 expansion slot capable of holding a half-length card, which I think is up to 175mm (6.9") which does seem pretty long to me for a case that is only 12" deep.  However as you point out the PSREF also mentions full-height card, which is obviously incorrect for a SFF case.  So I'm at least skeptical that this case could hold a low-profile graphics card approaching 175mm in length.

 

Now the PSREF does say that the P330 SFF can come with a P1000 card, which I believe is 5.7" (145mm) in length.  So we know that works.

 

The M910s SFF case was 11.4" so the P330 SFF at 12" is  .6" (15.4mm) deeper.  So if the max length of an x16 low-profile card for the M910s is stated as 150mm, it seems that the Zotac card at 160mm would come in at just a hair shorter than the probable at least 150+15.4=165.4mm max length for a card in the P330 SFF.  And it should certainly fit if the max length for a card in the P330 SFF is genuinely "half-length", or 175mm (but that number really seems impossible to me and surely is a mistake).

 

Probably worth a try, assuming you must have a SFF case.

 

As I mentioned previously, the new tower cases are really not much bigger than the SFF case (although at 12.5" D they are definitely 1.1" (28mm) deeper than the SFF case, which for sure lets them take a card at least 178mm long. In fact the tower PSREF claims it can hold a full-length card of 268mm (10.5") which seems impossible to me.  But the real problem with the SFF case was that while the motherboard length might have been adequate to hold a longer card, the swing-down drive assembly came down right over the end of the graphics card I had used rather than clearing it. So maybe the 1.1" deeper tower case really is all that is needed to let the drive assembly truly swing down far far away from the end of a pretty long graphics card.

 

Anyway, all I can really do for the P330 is speculate. You'll just have to try the Zotac card (like I was close to going to do in my M910s).

Thanks for your repid reply. Your comments are pretty helpful. Actaully I would like to have a compact computer so that I can place it on my desk. The SFF or Tiny series are perfect sizes for me. I think I will either give P330 SFF a try or directly buy P330 Tiny(This one comes with a built in Quadro P620 and is on sale for black friday).  One thing I concern about P330 Tiny is the noise level. I am currently using a Brix i7 4770r mini pc and it makes a lot of noise even with half load. I am wondering if you have any experience with Tiny series and could give me some insights?

Sorry, absolutely no experience with tiny machines.

 

But honestly, with the overall shrinkage of all new cases the new towers are not much "thicker" than the old SFF cases.  So you really could lie a new tower on its side and it would now not be much "taller" than the old SFF case was in that horizontal configuration (allowing you to place your monitor on top of the side-facing-up as I suggested to people who wanted to elevate their monitors but also get a SFF case).

 

Anyway, whatever you decide to go with if you post your reaction and comments here that would likely help others asking the same questions in the future.
