Or else there are two main power traces in the middle layers, and they somehow shorted. There is a crack in the PCB on the bottom there, along with discoloration around it. Maybe that's where the fire started. The traces had to be fairly sizable though, or at least large enough to conduct a lot of power without breaking right away - that looks like it had a sustained electrical source of heat.
I wonder how many case fans he has? Maybe the fire went out only because it wasn't getting enough oxygen. It did have plenty of plastic there to burn.
Wish there were higher res images.
It looks like the fire was mainly on the back of the board too. Yeah, I'd love more high res pics of it to compare the front and back.

Hm, I was thinking of getting the msi k8n neo2 plat, but now I'm not so sure. Anyone have one already?

Just a thought, but is that a USB header right at the bottom of where the fire looks like it started? I've accidentally crossed pins connecting USB headers in the past (antec case has each pin seperated) and noticed (luckily within a minute of powering up) that the wires were starting to get pretty friggin toasty.

I was thinking the same thing.. I had an Asus board with a couple headers...for some reason all the pinouts were identical, and one got plugged in wrong... I fired up the PC and instantly saw smoke coming from the case.. it just fried the cable, but a scare nonetheless. Almost does look like that's what happened... who knows for sure, and will never know now

My guess is incorrect pinning on the front USB connectors or whatever that little dual grey cable is on the left of pic 4 or towards the left end of the top PCI connector in pic 5.

I thought only the 68080 series and clones had this?

Owner of mainboard posts : I've had another email off them saying that if after inspection they discover it was a faulty component that caused the fire, they will replace the other items. Just need to send the board to them to find out now.

Ouch!

Probably a screw of board stand-off was misplaced and damaged the edge of the board shorting out the power plane layers (probably the +5V and ground).

I'm slightly surprised the PSU didn't shut off - to do that much damage must have required a lot of power for a long time.

Basically it looks like the motherboards internal power planes were shorted at the edge of the board (where the main damage is) - or possibly the 5V power plane shorted to the chassis (I'd like to see pics of the case to see if there is any damage).

It is very unlikely that the problem was caused by a loose, or improperly connected wire (the wire would be completely incinerated before the mobo was significantly damaged). Similarly it is unlikely that this is a manufacturing problem with the mobo. The most likely problem is incorrect mounting which has led to damage.

I suspect the melted PCI slots came from heat gerenated inside the mobo in the +5V power plane (or ground plane, but see above). Since PCI slots connect through the mobo they have good thermal connection to the power plane, so high temperatures in the mobo can easily escape into the slots.

The ONLY and LAST msi board I had had blown ALL of its caps within 2 weeks. MSI=DEATH.

This is what I observed. Also, there is a lot of dust there, and the two could have caused the fire together.

Well I hate to be the bringer of bad news but. Judging by the pictures provided it would appear that one of 2 things happened.
1: A screw of some variety got caught under the motherboard at the bottem of the case, shorting something out, heating up and inturn melting and lighting your stuff on fire.(it would appear the case is very dirty and probably the starting fuel was dust in the bottem of the case)
2: you put the USB cable on backwards. For many years I worked at a custom shop and used MSI boards and have personally put a USB cable on backwards and it did infact cause a short, pop, heat, and a small flame when the computer was turned on. Never did that again. It would appear to be what happened here as well and inturn lighting the dust on fire and catching the board/cards on fire.

But again judging by the pictures I really don't think it was a hardware fault. Chaulk one up to experience.
