Id worry about customs/police in sweden. They are not like in the states, they have authority go in and check on you pretty much if they feel like.so maybe a package of real expensive hoeticulture lights at customs can be enough for them to take a look at how your powerbill switches on and off every 12 hours and thats a giveaway. But if your only importing chips and power supplies etc you should be cool.
Funny story: some guys i met got busted for somkin in their house. When the cops came my mates asked for a warrant and got laughed at by the cops: they were told they watch too many american tv shows and that its an onsite decision by the comanding officer. Stay off that radar!
My highest priority is to stay off that radar, i dont want anyone knocking on my door, ever
