Yes, the internal frame is virtually identical; the main difference is that the front LEDs and USB ports are attached to the frame instead of the bezel. Also, the NSK4400 has only one hard drive activity LED instead of three. It's an evolution of the original SLK1600 series, which originally had a 92mm/80mm rear fan mount and a less refined hard drive cage (no rubber grommets), but which was otherwise the same as the latest incarnations. Any of the bezels and exterior case panels can snap onto any of the frames.
However, I would quibble with your implication that the newer SU-380 power supply is only "a little bit better" than the older SmartPower 350. The SU-380 is a LOT better. It has a strong resemblance to the Seasonic Super Silencer and the new Seasonic S12 series, as you can see in the following review:

As you know, the NSK4400 has been discontinued. It is being replaced by the NSK4480, which is almost identical except it has an EarthWatts EA-380 power supply.
The SLK1600/SLK1650/NSK4400/NSK4480 cases are much better than "cheap" cases and a couple steps above the typical "budget" case, and they are very solid. I bought several SLK1600/SLK1650s over the years for $9.99-24.99 after rebate, which I considered to be a great deal. I like the fact that they are "compact" ATX cases. They are more than 1" shorter in depth than most ATX cases, which accounts for most of the internal crowding. (The hard drive sticks out over the motherboard, and there's not a lot of room between the CD/DVD drive and the power supply.) There isn't really enough room for a long video card. But if you bundle and carefully route the power cables and drive cables, the air flow is just as good as it is in any other case that has a 120mm rear fan. (I use dozens of cable ties in every computer I assemble.) The Antec 3-speed 120mm case fans are very good.
I only have a couple of complaints. 1) The finish on the older SLK1600/SLK1650 exterior side and top panels could be easily scratched and they show a lot of fingerprints (I'm not too sure about the NSK4400, but it seems to be the same at first glance), and 2) removing and replacing the panels is a pain due to the way they're designed. Once assembled and screwed down tight, though, they are secure and they don't rattle.
My favorite case by Antec is the NSK6500/NSK6580, mainly because I like the internal layout. I bought a couple of NSK6500s at Fry's a couple of months ago for $69.99 plus tax (no rebate), and I reckon there will be even better deals in the future if Antec ever decides to offer rebates for the NSK6580. For that matter, Antec will probably offer rebates for the NSK4480 in a few months. So even if you missed out on the current deal, you might get an even better deal on an NSK4480 or NSK6580 in the near future. One thing is certain, Antec offers lots of rebates (the checks have always come through for me), and the deals are pretty good.
