Bear in mind that all of lowest connectors are to be removed. You may also encounter some problems with chassis connectors under the lowest gpu...

So maybe I should first try to lower the Titan Black one slot downwards. If that fits, try and move the fans to the top of the Noctua's. And if that also fits, order the two 780's?

It will fit - some time ago I assembled 4x titans on such a motherboard. But first connect chassis power cables, remove usb cables and then insert the lowest card. It may happen that you'll need to bend slightly power connectors to insert the lowest card (be very careful with it).

So I tried lowering the Titan one slot into the blue slot. But the Front USB 3.0 cable (wide one with the blue socket) was in the way. I tried bending it, but when I put the card in, it didn't fit and the cable sprung loose.

Are there maybe cables which have a smaller footprint? OR should I place one of the 780 there because that card has the fans on top of the card?
Then I proceeded putting the bottom Noctua fans to the top. So I removed them from the bottom and put the brackets and black plugs on the other side of the fan. That's how I was supposed to do it right? To keep the same airflow?
So here are the fans on top, creating more room like you guys said. Then I tried putting the Titan Black in the first slot to see if there was enough clearance created.
It's JUST enough clearance, I could lift the Noctua a bit because it's leaning down a bit through it's weight. So maybe use a tie-wrap or something to lift it up a bit?

But the thing is, I'm not sure about what the Order of the cards should be? Could you guys shed some light on that?

The Titan has it fan on the bottom, but the 780 has two fans on top. Won't this interfere with each other? And I'm confused in which slots the cards should be exactly.

I was also wondering about the PSU, is 1050 enough for three cards? Or should I go up to 1200W or even 1500W. I can remember I read something in the article, you did both, about this?

And one other thing is, I believe you mentioned to also upgrade the case fans? Is this necessary? The are 5 case fans in total now. Two in the front, which could be of more use when I would be able to remove the HDD trays. Plus one fan in the back, one fan on top, one fan on the side and one in the bottom. (Three of those fans are Fractal Design Silent Series R2 140 mm)

As said earlier - remove all cables from lowest slots - including USB. Leave only chassis power connectors to power up your computer.

Get rid of these noctua bulky radiators and replace them with something smaller and neater.

Ok so that would mean no USB 3 on the front. But I could use a USB hub for that maybe.

And should I put the Titan as the lowest card? And the two 780's on top?

Are the 780 6b? They will produce lots of heat into the case and slow down your titan. Put them on the bottom.

Yes I was planning to buy the 6GB versions.

So if I would place them on the bottom, they will blow to the top right? Towards the Titan, which has the fan on the bottom. That won't be a problem?

BTW try to remove unnecessary drive cages and put ssds neatly - make more room for fans that are in front of the case
