	Which makes me think that I will use Software Raid 5 and convert the  
price of the card into RAM.
	This should be nice for a budget server.
	Gonna investigate now if Linux software RAID5 is rugged enough. Can  
always buy the a card later if not.

	Thanks all for the advice, you were really helpful.
