I just bought a new in box Asus PC-DL dual Socket 604 Xeon i875P motherboard.
The price was reasonable considering that used boards are costing 200 euros and up on Ebay because this is considered to be the top motherboard for running dual Gallatin Xeons... So yea only an arm, a leg, a kidney and part of the liver... I also got a mail fordwarder in the UK and bought a couple of 3.2 GHz 2MB L3 Gallatins to see how they compare with my 3.2 GHz 1MB and 3.0 GHz 4MB ones. Other than a few much cheaper motherboards in my watch list, Xeon cooling and perhaps a couple of cheap CPUs I'm done with spending money on retro hardware for the next half a year or so.
