It's an excellent cage for a Syrian hamster
It's a good size and has a really nice big front opening door, so good for access, and getting things in and out, and for interacting with your hammy. Hope it arrives soon! They can take between 3 and 7 days depending whether you ordered before a week-end or not usually.
The shelf has a white house with holes in on it which could do to be taken out (not the shelf, just the white house) as the entrance holes are a bit small for a Syrian and if they grow big they can get stuck in holes that are too small. But the shelf is fine without out and hamsters do better with a house on the floor of the cage on top of the substrate and open underneath, so they can bury hoards under their nest and so on - plus it's easier to spot clean like that, without disturbing their nest too much. A shoebox house can be good. Cut the bottom out of a shoebox and a hole in the front for a door and you can use the lid as a lift-off roof so you can check inside the house without taking it out (so the nest doesn't fall apart).
Did you order a wheel from Zooplus as well? I would recommend getting a potty litter tray. Hammies tend to use them if you put it in the corner/area they choose as a pee corner. Most people put chinchilla bathing sand in the potty (it's a bit safer than hamster potty litter and works out cheaper I find).
I use this one

And this is the chinchilla sand - it's quite a big carton. I get two at a time to save on postage costs.

So just fill the base as high as you can with substrate, wheel, house and a few toys (cardboard tube, hidey places etc, a chew stick, and your hammy is set to go. Plus food and water of course.
