The Chenbro Junior is *not* a GENIE, contrary to the impression that the front bezel gives you. As BMF and jfh point out, the internals are a completely new design. This is a good thing, resulting in a slick hard disk cage setup but results in some design quirks. Extensive explaination is therefore included on quirks of the Junior.
The Junior, like the GENIE before it, is a wide case. At 18.5"x8.75"x17.75" (HxWxD) it stands noticably taller, wider, and deeper than my Enlight 7237, but not by much in any direction. With 3x5.25" and 2x3.5" exposed bays, it loses an exposed 5.25" bay from the GENIE as well as three internal 3.5" bays and most of the LED lights. It retains side panels and a removable, two-part front bezel; like the rest of the case the design of both pieces is different from the GENIE.
According to jfh, the side panels are of the same design as on conventional Chenbro cases. A thumbscrew removes the top panel, which slides back and comes off. A single screw holds each side panel, then you life a handle and the panel comes off vertically. You do not need to remove the front bezel, which makes things easier for those who use harddisk coolers, especially the Globalwin IStorm. The front bezel requires the removal of both side panels, then four plastic tabs are undone and the bezel can be removed. Reinstallation is accomplished by aligning the bezel with the top of the case, then snapping it back in place. The system works well, but it is very different than the GENIE. The power supply is mounted horizontally, not vertically like the GENIE. The harddisk/3.5" cage is integrated into a single unit- a metal locking tab that you squeeze, then pull towards you unlocks the cage. There's no front intake filter although one could easily be fitted. The front 80mm looks blocked from proper intake, but upon inspection it appears to breathe fine.
Features common to the GENIE and the Junior: a standard Ya Hsin 300 watt PS, a set of hybrid 92/120 fan mounts (one in front, one in back), drive rails, screw-on metal covers for the exposed drive bays, and a front bezel with a removable intake cover. Excellent airflow is also standard- jfh's stock configuration is 74.5cfm/36dBA (120mm) intake + 34cfm/30dBA (80mm) intake plus the PS exhausting (~35cfm?). For less noise Panaflo L1A's should be a good substitue; I will perform such testing later.
Intake is a 120mm and an 80mm in jfh's standard configuration. No separate exhaust is standard; with open area and venting it probably is not required. The 80mm is in-line with the 3x3.5" internal HD mounts, and is more than adequate for HD cooling even when the cage is full. A 92mm HD fan could probably be fitted for those who need the extra cooling. A free-flowing path for air and the 120mm intake seem to allow for sufficient airflow through the case. In the back, additional 80mm exhaust fans could be fitted above the expansion slots with some work; I haven't tested this and may not as the ~100cfm standard exhaust potential is plenty. The card holder has a slot for cables to be routed through, which is a nice touch.
Quibbles: The card holder (easily removed with 1 screw) obstructs the 120mm intake *slightly* and doesn't seem necessary for most. Reset button is stupid- you need a pen to push it. The front bezel on mine does not fit flush at the middle, and my 120mm intake seems to be making some mechanical noises on power up/down. With the exception of the first two, these problems are probably specific to my example.
Conclusion: An excellent case with some notable design quirks. ~100cfm intake and ~100cfm exhaust potentials offer excellent cooling. The Addtronics 6896a has better construction but is closer to the GENIE in size. Nothing in its class seems to compare exactly so identify your needs first.
