Ooh I love the Rodipet house! It's a great house, and solves the food bowl and water bottle placement! She will love it! It's probably big enough to put a hamster litter tray inside as well if you find she decides to have her toilet in a corner of the house. I tend to wait and see where they decide to choose a pee place, and then put the litter tray there. If you want to tempt her into it to nest in it, you could try putting a bendy bridge over the door (I find they tend to go straight down dark tunnels lol). Just thinking if she had a few options she might decide to nest somewhere else.
Looking forward to meeting her and seeing her cage. You can have all kinds of boredom breakers. Paper balls with food in sound fun. Chew sticks, antos vegetable chews or anything with food stuck on are usually popular! (And good for their teeth as long as they aren't too sugary).
Have you seen Erin's Hamsters 10 toilet roll tubes video as well? it shows how to make little food parcels.
