Thanks for the responses.
I should have been a little clearer about width and depth as in my current setup those can be no more than 14" a piece. While the Norco or the ATX tower would server my purposes, they won't fit in the space I'm looking for. Once I'm in a new place and can dedicate a closet or back room to the electronics, something like the Norco will be my first step (I actually helped build out a Norco-based server for my girlfriend's father - but they have a back room behind their projector screen for electronics so it was easy.) As it is, this has to fit in my entertainment console and be pleasing for me, the girlfriend, and our guests to look at. (The giant APC UPS is frowned upon but has proven it's worth and so gets to stay.)
That's why I'd prefer something with a similar form factor to the Media Smart. Small footprint (but I can go a little bit bigger) and looks pretty nice. The Lian Li Q25 would be perfect if only it were an inch shorter.
Mfmusick, I've checked out the thread previously as well as the other server building threads. I'm aware of the unfortunate limitations of going the path I'm going but it's simply a path of some predefined parameters. If I had the room, the easiest thing would be for me to add an eSATA box to connect to the MSS but like I said I don't have the room. I did a lot of research before making the thread and the best options I could find I put in my original post, I'm just hoping that users with a lot more experience, like you and amarshonarbangla, might have come across an enclosure that I missed that better fits what I'm looking for.
amarshonarbangla, could a hot swap cage like that be added to an enclosure like the Node 304? I do agree, I think the 304 looks really nice, especially for its purpose to be seen in an entertainment center. Have you, or anyone else, seen anything with a similar form factor that does have a hot swap cage and is under 10" tall?
