Merry Xmas to you too.. I have two computers and in one I have DFI motherboard with Pentium II @ 400MHz on it, and had no problems with it. Second one uses Asus P4 C800 Deluxe MB with P4 @ 2.8 GHz, this one I'm using for one year now and never had any problems of any kind... So, I would recommend Asus, DFI, Soltek, Gigabyte MBO-s. You can't miss here As for the memory, currently using Kigston HyperX DDR 400 and it works perfectly.. I would recommend either expensive Kingston or even more expensive and the best overclocking memory Corsair... (that's just my opinion)
