Should add, in reference to JP's comments as my experience has been so different.The hard disk I fitted to this system is a Maxtor 40gb one and to date (admittedly only 4-5 days) I have experienced no problems - in fact the system is running faster than ever.
I run 2 sound cards on the one system both of which are Soundblasters and have experienced no problems. The 1st card is a Soundblaster Live which I use for most purposes. The 2nd card is a SB AWE 32 which exists to accept an old Yamaha DB50XG daughterboard for MIDI - probably just me but I much prefer the MIDI that old board produces to the news SB Live (which doesnt have the old connections to mount it).
