doesnt sound like a bad idea as you would save quite a bit of money (your comparing a standard halo to one with an upgrade board when you say £103.07 and £107.99) so actually it would be worth it... if planet had all of the parts... and you could be botherd to do it...
but you could get most of the parts on the classifieds anyway, if not buy a f*ckd loader and fix it.
