XPS 700 motherboard

Hi theoldworkhorse,

XPS 700 uses BTX form factor motherboards and would not be able to accommodate a mITX motherboard. You may consider purchasing a BTX form factor motherboards available online. You may refer to link Here.

As the BTX form factor motherboards have been discontinued, I did some research online and found an individual project in which a user was able to successfully convert BTX chassis to an ATX chassis and was able to use an ATX motherboard in it. You may refer to link Here. 

Note : Dell has not tested the above conversion and does not recommend changing the original system configuration.

For replacing the motherboard, you may refer to instructions in Service Manual Here.

Note :  Please refer to safety instructions in the manual prior replacing motherboard. 

Hope this helps.

I know that the XPS 700 uses the old form factor and that the new motherboards do not work. I was looking at the mITX, http://www.ncix.ca/products/?sku=71117&vpn=P8H77-I&manufacture=ASUS, form factor. Do you think it would work in the system as an upgrade. (My old board is now fried and I hate to waste a good,, all be it heavy, case. The psu is still good all so.

I'd suggest a replacement motherboard, and there are plenty available on eBay. Or, perhaps, your old board is repairable?

Would the miTX work in the case?
