During my research for two upcoming HTPC feature stories on building an HTPC and HTPC server I came across a couple of nice deals at Amazon (affiliate).
First up is the Apex MI-100 
Next is the Antec 300 Case which would make a nice HTPC server case for $50. It has 3 5.25 external drive bays and 6 3.5 internal drive bays.
