From MacBidouille:
After Promax and Wiebtech, Sonnet should announce at the AppleExpo an Internal Drive Mounting System for PowerMac G5. Its name, the G5 Jive.
This system consists of a custom metal base plate and mounting bracket, mounting screws, three internal SATA data cables, and a custom-designed 3-drive SATA power cable; in addition to the support for two internal HDs available by default in a PMG5. G5 Jive mounts in the space at the bottom of the case beneath the optical drive and its installation has zero impact on PCI slots and adapter cards, which is a key point also for many users.
The system includes all necessary mounting hardware and cables but the required Tempo-X eSATA PCI-X card is sold separately.
The price should be around 120US$.
We do not know what will be the impact of such a system on the air flows in the PMG5, we will have to see the final design to evaluate its interference with the cooling system.
