IMHO the things holding u back are the pump/res and your rad, i would recommend a Black ICE Extreme 120.3 or a Feser (TFC) 360 (120.3) and res - whatever takes your fancy really, but i always recommend the EK Multi-option, though the XSPC Res top for the Laing DDC3 is really good for flow, which is one of your issues with that XSPC res/pump. But not so u'd notice if u had a EK
