How neat is this? The pictures tell the whole story anyway.
This is the SATA HDD Stage Rack, which is a Mac and PC compatible device that connects via USB 2.0. Simply plugging in a hard drive ala Atari 2600 Cart style will allow the drive to show up on your computer. There are two versions – the 2.5" for notebook drives and 3.5" versions for standard desktop hard drives. The stage rack sadly does require an external power connection, however I know little else right now. It also has a glowing bl00 light – these things are important in any device! I can only find this device on Amazon US so far, but I want one!
My ‘Junk Cupboard’ is packed with old hard drives, mostly of the IDE variety sadly so I’m hoping that an IDE version gets released in future. The button at the front looks like an eject button to ‘pop’ release the drive safely too. Hopefully these devices won’t be too costly.
to this or anything else 
Saw these a few weeks ago, apparently there are two problems with them:
1. They aren’t eSATA and use USB instead
2. They aren’t eSATA and to add a HDD you need to turn the PC off, plug the drive in and turn back on
Think they are priced $30-$60
When will there be an IDE one arg!
