Do you have this version :

Or THIS version ?

When ordering custom-caps for a steelseries, you
really need to pay attention to the details .
'Standard' Cherry/Filco-sets will
not fit perfectly, due to the layout-weirdness caused by the HUGE-ASS Enter-key .
I have the Nordic-layout version and as much as I love the keyboard (It just has that good old 'bomb-proof' feel to it)
it's a bloody nightmare to pimp it ..
The nordic-layout requires caps from both a 1800 and 3000 series cherry board and you STILL
have a problem with 'Capslocks', 'Enter' and the cap that must be placed on a row it wasn't made for ..
