What size is my motherboard?

[ghodge101]

This is my motherboard (I know)

I was wondering if it is Micro-ATX or Mini-ATX or whatever. I'm trying to move all of my stuff from one case to another.

My PC is an Inspiron 660s btw

And when you guys find out, if you could tell me some cases too that'd be great!

Almost assuredly it will be micro ATX.

Almost assuredly it will be micro ATX.

Is there anyway to confirm? I've tried and can't find anything.

Look at the number on the board. CN-blah-blah.... Enter that in google and find out or post a link and we'll tell you.

Given the fact that it's prebuilt and a slim tower, it's almost certainly micro ATX.

It's not a standard micro-ATX board. Dell has a picture of the computer case with the side panel off on their website:

Dell states the case is 10.4" tall and the board is oblong, with a power supply on the bottom of the board. A standard micro ATX motherboard is 9.6" by 9.6", which would take up the entire height of the case. The board in the picture appears to be about as long as the computer is tall, but it is certainly no more than about 8" tall due to the power supply sitting underneath it. The computer's manual shows it has two PCIe expansion slots, whereas a standard micro ATX board would have three.

The only standard board size that is about the right size and shape would be DTX, which is 8" tall by 9.6" long and has two expansion slots. Think of a micro ATX board with the bottom 1.6" containing the bottom-most expansion slot cut off and that is DTX. I would have to measure the exact board in your machine to see if it is 8.0" by 9.6" to tell if it an actual DTX-sized board versus a micro ATX design where Dell cut off more or less than the "official" 1.6". Dell being a huge OEM makes a lot of loosely-based-on-a-standard custom parts, most notoriously their PIII era ATX-like power supply connectors but with the wires in a nonstandard configuration.

If you are trying to replace the board with something else and still keep the case, that will be a whole lot of fun as DTX boards never really caught on. People stuck with standard micro-ATX boards or went to the much smaller mini-ITX and mini-DTX boards for smaller builds. I see exactly zero standard DTX sized motherboards on Newegg, for example. Mini-DTX is essentially a mini-ITX board that is a fuzz taller and has two expansion slots instead of only one. The only standard boards that would fit your case would be mini-ITX and mini-DTX boards. The worst case scenario you will have to do is drill and tap new standoff holes if Dell used a nonstandard pattern.

If you are trying to move this motherboard to a new case, it probably will fit. The standoff hole pattern for all ATX and later boards is standard and they simply add or subtract standoff hole patterns depending on board size. Assuming the board is a standard DTX board or a cut-down micro ATX board, you can put it in any other standard aftermarket case which is large enough for it. Humorously enough, my router's tiny little micro-DTX board screws right into my giant SWTX workstation case, it simply uses four standoffs while the SWTX quad socket board uses 13.

Won't drilling into the motherboard hurt it?

You drill holes into the motherboard tray of the case to fit the motherboard's standoff holes. 😀 Drilling into the motherboard WOULD cause damage.

Oh ok! XD!!!! I was so confused!! But thanks! I sure do appreciate your help in this. 😀 so that would enable me to move it into another case? Just drilling the case to compensate for the motherboard standoff holes?

Try to install the board in the new case first, I would not be terribly surprised if the holes line up properly.
