the advantage of the rowe cd100 series (A,B,C,D,E,F,G,H, etc) is the all basically use the same parts. same computers...same amps... they all just look a little different. they all sound great. especially after the D series when the woofers where changed to 12's opposed to 10's.
the only gripe about the 100G (and the 100E series) I have is the ridiculous # of lights it has. the mini wedge lights (#74 mini wedge) don't like vibrations much and tend to burn out easily from vibrations from the woofers. It's worth your time and money to swap them out for LED lights.
Keep a special eye on your glass. it's tempered...and curved... a real recipe for disaster. replacements are hard to come by and you might end up replacing it with lexan or plexiglas if it get's busted. it never looks the same or as good as the original glass.
Just make sure you don't slam the door or open it by one corner twisting the front... it'll pop on you. tempered glass is a bear to clean up.
if you open it, 2 hands..one on either side. lift it straight up. support it in the middle while you clamp the struts with the red plastic holders. (if you have them or need them (some struts where weak)) If it opens and holds on it's own, you're golden.
other than that, it's a great sounding and a great looking machine. the infinite starfield look to the front really pops when you change the tungsten lamps for LED lamps.
