I wanted to get a dual drive with cd rom small enclosure since I like to test a few things here and there. I didn't want to use a four, six, or even eight bays since those are just expensive and they wouldn't be filled up with drives on my desktop. I also wanted something that was trayless and cheap since this is something that just sits on my desk gathering dust as most items you don't actually move do. I decided to use the istar version since it was the lowest priced version and it is trayless. This just makes it much easier to change things a little quicker vs. the tray versions. The other reason for this choice was the back of the unit. I can keep using the same cd rom cable which is sort of a two in one. The others have separate connections which I could still use but I didn't want to go looking for anything else I needed. Another plus was that there is no fan on this one. Not that it's a bad thing, but I know that two drives and the cd rom should not get too hot since the drive is not always needed and most likely only one drive will be use for the most part anyway. With that said here are the pictures.
Finally, the enclosure seems well made, but the door mechanism feels a bit flimsy and you really have to be careful opening it. Other than that there's not much else I can say about it. It's an enclosure and it's small enough to fit almost anywhere. However you will need another splitter if your case is small and doesn't have any extra power connector. I do like these other type of tray-less enclosures and hope we'll see more down the line.
Update April 12, 2017
I finally got a chance to make a print and get this part added to my desktop. I printed my own computer case which I have been using in different configurations for what I need. So here are a few more pictures of what I have done with this now. This is the same case that will be used for a nas and that's why I keep using it in different configurations.
Here's the final assembly or what it will look like. It was now working and there is a blue LED on each hard drive but I guess it turned of when I took the picture.
The 7 mm ssd doesn't fit like the 9 mm so that's why I think the light bleeds on the left since it's not sitting flat. I guess it moved up a bit so this is why I'll make an adapter to put on the top later.
