I've almost finished planning my build ( http://pcpartpicker.com/p/aNlR ) but I'm not sure what case to get. To fit in with my budget it needs to be between £30 and £40 and be a Mid ATX Tower. I don't need a power supply and in terms of appearance I'm fine with a plain black case. Sound isn't too much off an issue as well. Any advice or recommendations would be greatly appreciated.
