I've seen the Down and dirty CF-73 HDD caddy mod and it makes me think I can do same with this 30. I have quite a few 74 caddies and even more CF-19 caddies to use for parts. The connection strip for them are both sata in nature and will plug into the 30's connector. Just have to fab a decent case to house the hdd and ribbon in place.
I've already verified the connection compatibility of both ribbons. Used a HDD that had Linux on it and a set of long tongs to act as long skinny fingers for inside the opening. Machine booted with no issues at all. Just had a hdd hanging out the side of the enclosure by either ribbon. So on to the hard part, fabricating a sufficient carrier.
This ought to be a lot of fun.

Amendment: I do things like use Minecraft to test my experiments of this nature out. It did play but the game ran quite slow and jerky. However at this time I'll attribute that to not having connected to the internet and upgrading the OS's drivers. So it was functionally running in a limp home mode. Also tried a couple of live USB distros and know that it does run quite quick but has no touch screen at this time. Future upgrade maybe.
