This is my build - http://uk.pcpartpicker.com/user/nortycrosal/saved/#savedbuild_1368885. I'm attaching the motherboard to the case. I have 4 lots of different sized screws which came with the case. Very small ones, slightly bigger ones, some very long ones and some larger ones. The smallest are too small - the next ones up are as well. The long ones are far too long and would go out of the case and the biggest ones seem to fit to a certain point but then become very very hard to screw any further and i don't want to force since i might break the motherboard. HELP!!!
