If you're just bound and determined to turn your Mac mini
into a home media center
then be sure to check the matching enclosures from Japan's Kuroutoshikou. The external cases share the dimensions of the mini for easy stackin' action and come in a variety of configurations, all with space for a single 3.5-inch disk. The ¥2,980 (about $25) GW3.5MM-U2 connects over USB 2.0 for PATA disk expansion; the ¥3,480 (about $30) GW3.5MM-U2/HUB adds a 3-port USB 2.0 hub; the ¥3,980 (about $34) GW3.5MM-U2/S adds support for faster, SATA drives; and the ¥5,980 (about $51) GW3.5MM-U2/LAN comes with an Ethernet port for network accessible storage. Got all that? No problem, you've got until the end of the month before they hit Japan.
