A back plane I've got, I could figure out how to mount the 2.5" drives to the 3.5 " hot-swap carriers, but getting it to fit on a optical drive's chassis plate (preferably within the CD sheet metal case ducting for active cooling) is the fun part. Besides I'm not all that confident I can get a full version of a software package that will do the job under OS9 or in my ability to get it to run. This is a convenient way to keep a redundant pair of three (possibly four) drive backup units stored away for occasional use.

I've already got those high quality terminated cables and I'd much rather save the server box for a speed RAID Level hack

It's the physical packaging challenge that's irresistible to me, especially so with the additional complexity of fitting an adapted laptop slot loader to fit above the Drive assembly within in the available cubic with the proposed RAID hack. This is a MetalMiniTower after all. Tray loaders aren't all that great in vertical mode, even when designed to to so.

Add in in trimming the ends off the adapters and hard-wiring a power/ground line loom and SCSI ID settings to the bobbed PCB's.

There's also the aux PSU and cooling to be added to the available cubic behind the I/O bay and RAID 5 hack challenge to be considered. ;D

Quixotic hardware hack # . . . dunno, I've lost count. :

. . . and we'll have fun, fun, fun 'til the grlf takes the hardware away! :approve:
