Nanometer: buy putting rads in parallel you might gain maybe 5% in flow .. but i wonder if rad efficiency won't suffer from that, as halved flow in each of them = less turbulence and because of that i'm guessing possible little less heat dissipation. Also more spending on fittings (eg. for quality Y fittings, that won't cut flow like some 90deg ones), more overcomplified tubing.. It's purely theoretical speculation though, with no real test numbers behind.

Eh? Since when horizontal and vertical can be confused? :/
