Yeah, the MSI mobo is quite good. As for hard drives...
Forget about the WD Raptor. It's small and expensive. You don't need a server-class hd for gaming.
The WD1200JB should be enough. Save the $ for a Sony DRU500AX which burns
all recordable formats DVD-R, DVD+R, DVD-RW, DVD+RW, CD-R and CD-RW.
Intel´s really a highly interesting alternative these days. I´d choose a P4P800 or P4C800, if possible, with a 2.8C anytime over the XP2800 on nForce2. It supports HT, it has 800Mhz and is on par with the XP3200 on a number of occasions - plus, it costs less than the current state-of-the-art processors.
