Hi folks, I'm building a Besta/Framsta TV unit from Ikea consisting of a Besta base unit (120x38) and Framsta wall frame and panels, but I've come across a problem. The unit in question is as below: IKEA | TV solutions for flatscreen TVs larger than 37" | BESTÅ/FRAMSTÅ/INREDA storage system | BESTÅ/ FRAMSTÅ | Storage combination The back panel is attached to the wall and therfore flush mounted. My problem is running cables from the TV to the sources and mains. They won't fit in the sides of the unit and the only way I can see to run them is by drilling holes in the aluminium frame and then the top of the Besta unit. Has anyone does this and can confirm it is safe to do this? I have tried Ikea, nobody in the dept knows the answer and I can't get in touch with anyone in the assembly service! Useless.
