I really wish we could get our hands on the Icy Dock FlexCage MB975SP-B price because we really like it. I don't mean we like it enough to want one, or even two. We want one for every server we have and we don't even want to stop there - we want enough bays to cover all of our HDD's. Hey, I review this stuff, I have quite a few HDD's, and after working with two FlexCage products, hot swapping HDD's with the cable and sitting on the desk just doesn't cut it anymore.
It's safe to say that the FlexCage MB975SP-B will tip the scales on the lower to mid of the $100 range. The previous generation, MB455SPF-B, is on Amazon at the time of writing for $113.33. The new model has an updated modern look, SATA III compatibility and SATA power connectors rather than 4-pin Molex power. 4-pin Molex connectors are now out of favor for every component other than fans.
Assuming the FlexCage 5 into 3 adapter comes in around the $115-ish price point or so, it's a solid buy. Similar products from Sarotech, Orico, Chenbro and Norco all cost more and some cost significantly more. At this time we don't know the price though, we're tossing the $115-ish amount out as wishful thinking. Even at $130 mark, the Icy Dock MB975SP-B's quality still fills the gap.
