I see the cage picture in your profile Poppycorn, perhaps you just needed to refresh your computer to see it. It looks like you found yourself a Superpet Crittertrail cage. I just bought one for my dwarf Roborovskis. Here is a picture of mine.
I had posted a thread about it here...

The Superpet Crittertrail I found was also very dusty and had a part missing, they gave me 20% off :P
Superpet Crittertrail cages appear to be made for syrian hamsters, I assume this due to the large sized wheel, Ive never seen an actual box for the cage. But in my opinion this is to small for a grown syrian hamster. The tubes that you can buy as a way to extend the cage are often to small for grown syrian hamsters and I've heard stories of them getting stuck in the tubes
The measurements equal the size of ten gallon tank as far as floor pace goes, give or take an inch.
It seems to me pet supplying companies never make their enclosures the proper size for caged animals. I would have only recommended a cage such as this to someone that has a dwarf hamster.
My syrian Gwen is kept in a 29-gallon tank. It measures 12 inches deep by 30 inches long. Plus I have added a second level. I would have recommended a bin cage. You can buy a good one for less then 15 bucks. All my bins are roughly 14 inched deep and 28 inches long. You may find that Poppy will grow out of her cage fairly fast. If you ever feel like the cage is to small, I would hope you will consider a bin cage, as they are in my own opinion the best way to house a syrian hamster. Unless you dont mind spending more money on a large tank.
