Just recieved my P4S61 board from ASRock today, thought id mention a few things for those interested. The board comes w/ 3 DIMM slots, the first one you can use pc3200, the second pc2700 and the third pc2100. There is no 4-pin power connector for the board, only the atx connector, ill be installing it in the next few days and will add any more interesting info here.
