Are you determined to use one of the older style hyphencubes or are you open to other options? Get ready for wall o' text n links either way.
Guess I'll run down what I know of the options in order of no particular:
-JBJ also has a nano-cube with LED lights and they also offer one with a metal halide light. The LEDs aren't the right color temp for planted but the metal halide allows you to choose a bulb that suits you
-JBJ also offers a rimless tank without a hood, light it however you want, looks ridiculously sexy imo, almost as nice as the Innovative Marine stuff
-Oceanic also has bio-cubes with metal halide lighting which apparently offer improvements in the rear filter chambers.
-The Red Sea Max 130 or 250 are IMO, much nicer and seem a little better constructed but still limits you to using a hood with integrated lighting although they have several options, including LED and T5HO.
-There are also the Innovative Marine tanks with glass tops (or open top) which obviously opens the door wide to whatever you want.
-Current USA offers the Solana with a bunch of lighting options but the price is pretty up there, however it is VERY nicely constructed of high quality materials
Basically what I'm saying is that you don't just have to choose from two or three options now, you can pretty much buy whatever you want/need in an all-in-one cube tank.
That comes with some limitations since most, if not all of these tanks are primarily geared towards reef keeping and that means the filtration is less than ideal for freshwater and the flow is probably going to be way too high for most fish.
I've got an 25 gallon version of the Solana from Ecoxotic that is no longer available and I must say that it looks great (low iron glass) but the rear filtering chambers are no better in design than an early generation biocube, which is to say they're pretty crappy and not really suited to freshwater fish keeping because they don't actually filter very much in the way of particulate. Perhaps some of the currently available tanks have improved, I have no way of knowing but I found I had to change the pump out for a much lower flow maxijet, and I've had to mess with the way the filtration is set up by removing all media except floss and adding about 2 pounds of bio media. It still doesn't filter particulate very well and I find myself siphon vacuuming the floor of the rear chamber every 2-3 weeks which involves pulling a bunch of stuff out of the way to ensure I can get at any muck in the corners. My wife found the same problem with her Biocube when she had it as a reef, but with her low fish load she found it was only once a month that she had to vacuum the rear chambers out but it was still a pain in the butt.
I'm not trying to turn you off the cubes as they can make beautiful tanks, they just have some special requirements that you probably ought to know in advance.
Feel free to check out my sig, it's got some old photos (really ought to update) and details a little of my trials and tribulations in adapting a salty cube to a planty box.
