It took me ages to put it all in, but, it works
1 Major problem left 
My emu 1820m card isn't producing any sound... but it is sending power to the breakout box so it's plugged in... I'll try and reinstall the drivers, if this is broken, I will be massively upset as it cost me £350 and is one of my pride and joys!
Anyway,
I had to take the whole thing apart, an back, and apart before everything was ok (loose connection first time I think in something, idk).
Lessons:
1) Don't buy a ****ing awful PSU. That thing is a POS and there was nothing on the description to indicate to me it couldn't handle anything I put in it. I'm a noob and thought 500w = 500w and only silly people spent >£30 on a psu.
2) Don't buy a ****ing huge PSU if you bought a value case (small)
3) Don't buy value anything. I should have bought a case and mobo seperate.
The PSU just fits inside, the cables are a royal mess but I tied them away from the fans/ventilation etc so they should be fine. There jsut isn't enough space in there, an the PSU cables are really long and multiparted (obv expecting a bigger case). But it went in eventually. I wouldn't recommend anyone else get that combo though.
On to trying to fix the sound card... please, please work
