My Netgear ReadyNAS as finally seen the end of days. It was a good little box for what is did, and more importantly, it was very low powered. Since I have been traveling around with a travel trailer, I am looking for a case that is low profile. Specifically, I am looking for a case that can hold 4 3.5" drives, and is not too much larger than my ReadyNAS. I know what the ReadyNAS is very small, so I don't expect to see something that small, but I don't have the space for anything like a tower.
