Going very old school. BTX form factor

Jump to solution

I have a NOS D955XCS mobo I need to get into service.

Made by Intel and I believe used in early versions of the Dell XPS series.

Here is my problem. It is about an inch too long for the Dimension 9100 case I had planned on using it in. Board to tray holes are off by just about that much.

Old BTX cases can be found out there. Usually at a decent price.

Shipping being more then the price of the case.

What I am asking is, just what Dell model case is large enough to accept this board.

Thanks in advance.

0ldsch00l,

Unfortunately, I have no information on which Dell case the motherboard will fit it. My database does not provide me with this information.

Most all Dell cases DO NOT USE standard mounting so I would say none.

Dell tends to mount the board into a tray and then slide in.

BTX Specification* Version 1.0b, July 2005, Intel Corporation

 BTX on the other hand uses holes and spacers in SPECIFC locations.

Thanks Jesse L.

Perhaps your info may provide case dimensions?

I am pretty sure any BTX case larger then the Dimension 9100 would work.

Is the 9100 considered a mid or full size tower?

Just do not want to spend the $$ on having a wrong used case shipped to me.

Thanks for the reply.

The mounting hole pattern is not the real problem. The hole pattern on both tray and board match perfectly.

The case size, to short(?) does not allow them to align.

After digging up the info available on the board it seems Inel made it for Dell.

References to it being used in the XPS series were found also.

However. There was a point when Dell went away from a more "custom" case for the XPS to a case closely resembling the Dimension.

Thus my follow up question. Which has not yet been Mod approved to appear, about Dimension case size(s).

0ldsch00l,

I hope this information helps you out.

The 9100 BTX Sleek design case is a mid size tower. Below are the dimensions.

Height 44.45 cm (17.5 inches)
Width 16.764 cm (6.6 inches)
Depth 44.45 cm (17.5 inches)

Mitac-designed, BTX case

Thanks again Jesse L.

Comparing those measurements to my 9100 seems to show me it is a mid size.

That answers that.

Would it be possible to get me the measurements of the BTX /XPS or Dimension full size towers?

The current model I have does not have the removable mobo tray, At  least as far as I can see.

There are no "standard"  mobo stand-offs as is the norm on all cases today.

There are actually stamped risers with threaded holes where screw in stand-offs would normally be.

The same with the processor heat sink,, fan shroud, and fan.

Which draws air directly from the front of the case as opposed to the more normal "fan directly on heat sink" setup.

Try motherbnard.org or something like: BTX form factor guide. My Opti 380 desktop(DT) uses a 10.5"x 12.8" mobo. It is std. size. I believe there were 2 smaller size BTX mobo  made: nano & pico. The 380 will accept all 3 sizes. If it's true what another visitor said about non-std bolt mntg, Then use a diff tray also. Mobo dimensions can be quickly found on Wiki...type in BTX motherboard wiki. I also believe that all of the "tower" versions of 3 digit Dell's (380,580,780,980) will fit your board.. Keep looking.

Thanks. Will follow up on those links.

My board measures 11.5 x 12.75 +/-

Sounds like you are correct on Dell`s naming scheme. 4 digit names may be mid-size while 3 digit are full size.

The bolt pattern and spacing are identical to the board currently in the 9100 case.

It is only the overall size of the D955XCS that will not allow it to fit.

I wish Dell would have used some SATA 3 boards in BTX.
