Hi - it for a Cannondale M800 - and I think to maintain the look I would need to aim for the 32 hole 231 silver all sides (I think that is rim 3 in the photos).
Being realistic about the cost of building the wheel (vs. picking one up prebuilt) probably £15 is what I would want to pay + the postage.
However I appreciate you might more.
Let me know if that looks workable.
