A report from Alexis:
Thanks to the news published in April 2006 explaining how to connect an external SATA drive to the internal port of a Mac mini, I could complete the following "bidouille": design a small but highly performing server.
I modified a Mac mini 1.66GHz Combo obtained from the Refurb Store to boot from an external 500GB Macway HD via SATA.
Thanks to the gigabit Ethernet port, I can play uncompressed HD video in 1280*720 from the Mac mini through the gigabit network, in other words 60MB/s
The difference with previous SATA modification: there is an eSATA port between the Mac mini and the external HD, it is easier for handling both devices, and one does not need to modify the HD.
