@garciaperales Well, the boards cost €300 including transport, about €25 for nails and screws, €20 for brackets, €10 for sandpaper, €5 for drills, €40 for varnish and brush, €10 for a saw, €30 for cables, boxes, power strips and other electrical elements and I think that's all.

In total about €450 for table and shelf with power strips in both the table and shelf. I still have to give the table a once over with fine sandpaper to polish it, but that won't be much.

I bought the boards from an online store, the hardware from a Big Mat near my house and the rest from neighborhood stores.
