I've have fun out of HDD slots and am running out of space. So im looking to get a bigger case that has more space and slots. Any ideas which cases i should be looking at? Case is a mid-atx it says. and heres the link to the specs. http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02629593#N1095
