I went ahead and built the whole thing yesterday, because having waited with this pile of luscious components on my desk for almost two months I couldn't wait any longer to see what they could do.
I started out by looking at the case. Beuatiful case, excellent airflow design. But there was one fan upon which hinged the entire layout. Unfortunately, the Accelero X2 is too big to allow the original fan (which was on a special metal mount, see pic) to be there. Also, there was a duct attached to the rear fan (which was meant to be an intake one). The Infinity is way to big to allow that
So those two had to go, which meant that the airflow was buggered.

I turned round the rear fan to be an exhaust, and now that I've built I see that I should be able to stick at least an 80mm exhaust where Lian Li wanted it, once I've cut a hole in my window panel. Then I'll switch the rear fan back round and alter the arrangement of the Infinity. The main problem is that while the CPU is cooled beautifully, the graphics card is rather hot, as the Infinity prettty much hogs the exhaust, and the only other is in the PSU at the top of the case.
Anyway, onwards!
Quickly installed the PSU:
The installation of the HSF was relatively easy.
Only minor problem was a little blob of metal joining two parts of the Skt775 bracket which were meant to be able to move relatively freely, but the Dremel quickly got rid of it. After that it was just thermal goo and mount:
Now I mounted the mobo in the case:
It's nice and high because of the space at the bottom for another PSU. I'm planning to use it either for some fancy-pants modding, or probably for sticking pump/reservoir when I watercool.
Next was replacing the x1900xt's stock cooler with the accelero, which was relatively easy. Just had to undo a few screws and remove the cooler, clean the GPU core and stick on the thermal pads before attaching the Accelero itself:
Finally I installed and hooked up HDDs in the removable cage and put in the DVDRW drive, hooked everything up to the PSU and....I couldn't get the 12V ATX connector in because the massive Infinity was in the way. So it was mobo back out of the case, plug in the connector and remount. After this minor debacle I plugged in the rest of the cables, did some crude tidying (the front panel ports are in one of those twisty plastic tubes and the IDE cable from the DVD drive is cable tied to it. The power cables need some more attention; the cable to the two HDs will be routed round the back of the mobo tray as it's the main offender.
Voila:
The next steps are cutting a hole for the side exhaust fan, rigging up some lighting (I'm thinking blue and orange, probably will make string of LEDs myslef), and possibly an etch on the window(nothing huge mind

)
Also I considered doing something with a 5.25" bay, just don't know what yet
