Are all motherboards universal fit?

i obviously realise micro cases are smaller etc, but do all motherboards have the screw holes in the samp place as all case stand offs? or are some different?

^ Correction: ATX cases can usually hold Micro ATX boards. I have seen cases that are ATX only (didn't have pins for mATX)

most cases these days support ATX, mATX, and some still support baby AT for some reason.

thanks for the advice, i was thinking of building my first custom pc, i was looking at a cheap atx gaming case, would a p5n-e sli fit?

See my current pc is:

X-Cruiser Case modified with extra side fan
Asus P5n-e sli
8800gt 1gb
q6600
sb audigy
4x1gb ddr2

because it will be my first ever attempt at a custom build, i was going to buy a cheap case, the one i seen looks like http://www.bluechip13.co.uk/images/super/535716.jpg its a atx case. The idea is with this atx case put my p5n-e sli in it, along with a blue orb ii,core duo cpu,250gb hdd and a few other things in. I was then looking at a new mobo for my x-cruiser to allow me to overclock the quad to 3.6ghz and higher, with a thermalright ultra 120. Would my p5n-e fit the atx case?

cheers

yeah i know, my x-cruiser has pretty decent airflow and i can overclock my 1gb 8800gt no probs, the case i showed will have a less powerful card, maybe a 512 8600gt or something so in terms of good airflow case that one should suffice. Its my first custom build pc i will put together myself, if i do a pretty good job could sell it on and customise a better one, of course with better airflow etc

As the pc im on now is only around 5mths or so im looking to upgrade a few things such as heatsink, mobo, so this new custom build project will get my p5n-e and blue orb ii. ive got a couple of case fans lying around and whatnot, so if i get heat problems on the new rig i can find somewhere to attach them inside. Ive been looking at cheap core 2 duo's for it, the rig should be something like:

Black ATX Gaming Case
Asus P5N-E SLI
2x1gb DDR2 Corsair XMS2@800mhz
250gb HDD
8600GT 512mb maybe
E6600 Core 2 Duo cooled with TT Blue Orb II
Then i might chuck in a basic sound card

Im basically stripping a few things out of my new pc and putting them into a new custom build, then upgrade my main x-cruiser pc. Hopefully can build it and sell it triple the price

i do have a question maybe you can answer geofelt, regarding gpu heat my 8800gt 1gb has the stock shroud heatsink and small fan, i tried to remove it the other week to put some mx-2 paste on, but the shroud wouldnt come off. all screws were out, and i could see the heat pad things but the darn thing wouldnt come off. I was thinking of putting a duo orb on the card, but im not going to order one if i cant get the stock one off.

Any tips? Ive overclocked the card to 738/1635/905 which is only just stable, any higher it artifacts, idle - 54c load - about 70c+

Cheers

ok thanks, when i get round to buying my new mobo will order that heatsink for the gpu seems to cool it a good 15c or so, will play something for a few hours and switch it all off then do it all then.

sound advice, cheers
