Here's some pics of my install.

I decided to install the LCD in the case for a true console feel, and I never really liked the idea of a bare ribbon cable.
The fact that the ribbon cable is plugged in from the top makes it kind of hard to have a neat install, so I removed the header and replaced it with 2 rows of fresh pins on the underside. In order for this to work you have to flip the cable then flip every pair of wires.
I'm really happy with how the whole system has turned out, Thanks guys
Things to note:
I had to cut the locator off one of the plastic support legs of the Darksoft PCB else it would hit and crush a capacitor when I installed it.
Pressing the connecting PCB flush on both boards causes the main board to bent, so I left around 2mm of pins showing from the rom board to keep the main one straight.
The LCD ribbon cable connector sat too high from the main PCB and stopped me from shutting the case, it would just rock on the connector.
So I had to superglue the connector together then cut the top support bit off.
Was only a few mm that I needed. Maybe your using a new cable supplier?
