The first case (HS-1) is just another Chieftech(?) relabel.... These cases are quite abundant on the web, all going for about $100, so this is a lukewarm deal at best.
The second case (HS-2) is basically the same case as the first.....same internals, the only major diff being the plastic front bezel. Yes, I said plastic! It's molded/painted to almost match the color of the aluminum, but not quite. Anything less than 3 feet away, and you can tell it's not an aluminum front. I was just at Fry's today, and got a firsthand look at this case.... BAH! Very dissapointing; I wouldn't touch it with a ten-foot pole. You could make a stronger, more durable case using beer cans, or aluminum foil - the metal is just that thin! Oh yeah, one other thing...I'm now wearing a bandaid because of a slice I received from grabbing the case to look at it. Damned sharp rails in there.
On the positive side, if you are looking to build a very low budget rig, and aren't going to be moving it around much, (LANs, etc) these might be good starter cases for you. Just remember though.....You DO get what you pay for with these.
