Cases with (Unofficial) SSI-EEB Support

Time for giant boards in small-ish cases again.

So I’ve been shopping around again for a cheap, compact case that I can stuff a surplus SSI-EEB motherboard into. On one hand it’s not going great, but I’m finding that there are a lot of cases that do have most mounting points for SSI-EEB but don’t mention it anywhere in their advertising materials.

I’m gonna start a thread here that I’ll try to keep updated with cases that appear to support SSI-EEB/‘EATX’ form factors as I find them. If anyone has anything they’d like to add, please do link it below and I’ll put it on the list.

Inclusion on this list doesn’t imply that such a build is a good idea, just that the correct standoffs are present and a board will technically fit. I wouldn’t recommend some of these cases… a lot of them would absolutely cause anything of any meaningful power to commit sudoku, but it will fit.

Disclaimer - I only own a couple of these cases; judgements are otherwise made from overlaying a hardware diagram over product images. If you know something is inaccurate, please let me know and I’ll update accordingly.

:green_square: - All mounting points present, should work with any SSI-EEB board.
:yellow_square: - All mounting points present or missing in center of board, or restrictions/obstructions present.
:red_square: - Missing perimeter mounting points; will probably still work, but check if you need them.

Common Problems

• Missing SSI-EEB alternate top-left standoff near I/O shield.

The SSI-EEB standard allows for several alternate mounting points, one of which is directly behind the I/O shield. This isn’t a very common board configuration. I wouldn’t recommend mounting one of these boards without this standoff because of force applied to the I/O area.

I have an Corsair Graphite Series 780T (Mini-ITX, µATX, ATX, E-ATX) and placed an ASUS Pro WS WRX80E-Sage SE WIFI (E-ATX - SSI EEB) inside. It does not feature all screw holes necessary, but was able to mount it fairly well.

Deepcool Matrexx 70 have E-ATX support, but not sure about SSI-EEB cause the official website is really trash.
If the openings fit the standard ATX then it should support it just fine.
Matrexx 70 is an amazing case… Of course it have a couple issues, but then again don’t we all…

Oh yeah, looks like it does. Missing the optional mounting point by the I/O shield, but there are only a handful of boards that use that anyway. The DeepCool case I have is built way better than I expected for the price, it’s genuinely a nice case.


Whenever I have a chance (probably while I’m sitting in the office with nothing to do) I’m going to start adding a snapshot to each entry that shows which mounting holes the case does/doesn’t have.

That’s pretty much everything you could ever need. I’ll probably add SuperMicro’s EEATX, EVGA’s XL-ATX, and some other weird things to it someday. And then there are all the server board form factors meant for rack systems.

Hell, someone should keep a database of these. Maybe I’ll make another MediaWiki, put up another subdomain, and start cataloging cases there. :man_shrugging:

I recently installed a WRX80 Sage in a Silverstone SST-GD07B-C. It fits but the hdd case is reaching into the vrm heatsinks.

I’ve got a WRX80 Sage and an EVGA 1600W T2 PSU in a Fractal Torrent. It was tight working in there, and I kept looking at my Define 7 XL thinking maybe I swap it out.

But I stuck with the Torrent, mostly because I think I can put this case in a 22" rack laying on it’s side (if I cut off the feet). If that doesn’t work out, then I’ll be lurking in this thread looking for EEB cases that can lay on their side inside a rack :slight_smile:

I chuckled when i read that!

I believe the term you were looking for is sepuku
( ritual samuri suicide)
But you raise a very valid point, the case needs to ba able to accomodate the board you plan to use without case modification.

Yep - there are a lot of cases on here that I do not recommend because of poor airflow, no room for drives, no cable routing points, etc, but I’ll let everyone make their own decision on whether it will work for whatever they’re using it for.

Like the Montech X3. It’s got everything needed for EEB support, but it’s tiny and has room for nothing other than the board. Every cable cutout but the one meant for the CPU EPS power connector is covered. But, for something like one of Intel’s server boards with ATX power on the bottom edge right by the PSU shroud, it wouldn’t be bad at all for a workstation with some flash storage.
