First of all: thanks to all for bidding. Unfortunately the reserve price I stated in the OP was not met (35 BTC), and thus for the time being I'll keep the units and mine with them myself.
I thank you all for your business and the trust deposited in me, if anybody is willing to meet the reserve price please PM me and we can discuss it.
Starting bid:
4@1BTC
..so clever to start auction with 1BTC and not with reserved price.)
