I haven't seen one of these in years. Most of the FC200Rs with Clears were the black variants. IIRC EK had few white variants back when they were first sold in 2011.
Is an auction really a great find though? I feel like half of the find is the price. Unless something is ridiculously rare, but this isn't that hard to find.
I'd say a fairly uncommon find. People have various choices of boards with MX Clears nowadays. Back then, this was pretty rare especially since it was unheard of for Leopold to carry anything other than the usual Black/Red/Brown/Blue switches.
Great board (still use mine on my workstation rig) and a nice pick up for anyone who wants a simple, solid keyboard with MX Clears.
