Got both of my new cases, just need to wait for the power supply now, although I think it may be wise to also get a couple of fans for each case too, as I suspect that there isn't enough cooling in the current case, and there's no cooling fan at all in one of the cases! In the case I'm going to put my new rig into, there's room for 2 side fans, and a rear fan (none of which are installed), and in the case for my "new" rig, there is space for a rear fan (already included), 2 top fans, and 2 side fans (also a clear window), so there should be some decent cooling, although I am aware that the side fans face me, so I need to probably install filters as well to stop dust getting on me!
