Let the hive mind of Engadget get that for you.
"I commonly need to boot a system from an external disc and take a snapshot of the host system. I also then need to burn a copy of the image to a DVD. While I can do it with two separate external devices, and two power supplies, and two I/O cables, it'd be nice to find a small dual-drive enclosure. It would need to have USB, eSATA, and FireWire. Either slim-line or half-height bay for the optical burner would be fine, and space for either a 2.5- or 3.5-inch hard disc. Any ideas?"
As for 1GB of RAM: That's the standard and OS X gets on just fine with it, if you need to add more to use video editing apps then there's an option to do so or you can do it later and no longer need to dive about in the innards of the computer.
I mean at least try to be fair about the thing. I'm not a fan of how they showed the Dell with wires and the imac with none personally but don't knock the product if your criticism is not deserved.
