Entertainment centers, Plastic tubs, if you put them in the bacement or under the stairs. Or,
any unused space in the house.
As for the attic? only if you have a solid wood surface and never in-between the rafters my family has a wooden cabin and we store all kinds of heavy stuff in the attic. the addic should be the best choice but that is my opinion
(edit) if the attic is your choice, be careful I fell from an attic in my apartment before onto the floor. Take one console at a time I don't want you to drop any. or for you to fall from the attic like I did before.
