Ivar gets the semiplas toilet plunger from under the kitchen sink and uses that to suck a pair of tiles out of the kitchen floor. The hidden space below, now revealed, is where he hides the Cruncher and related hardware, such as his toolbox. He wouldn’t bother hiding things except the parole board doesn’t like him keeping cyberdecks around, and now and then they send somebody around to check. Of course, nobody glued his datajack shut, or, for that matter, messed with the tech inside his head, such as his expanded memory module and advanced data manager, so the parole board couldn’t have been too serious about wanting him to "stay away from computers." More like, do what you have to, chummer, but don’t do anything bad . Guy’s gotta make a living, don’t he? Well ... anyway.
