I thought of this too but found a very good deal on an XR5 so I just nabbed that. If I find when I eventually add a GPU I need more, I could swap the rad.Consider 280 GTS X-Flow, it has the same performance as the U-flow version but has very low flow restriction and it's much easier to drain. That's the best radiator for Meshlicious in my opinion. WCUK have some in stock right now, not sure if they ship to the EU.
Ended up buying a VTX 120 pump res too so I think pressure won't be a problem either.
