Any plug and play systems available?

[DeBruynB]

I had an operational system years ago, but since I moved in 2015 I failed to get it working again. It was also needed to have it hooked up to a pc 24/7. But I want to contribute again with a system that is stand-alone (blue system can do this I think?). But I'm a literal 0 at electronics, so I'm wondering if there is any plug and play systems available or someone who assemble these things for a price? 

Thanks!
