Initial thoughts were to just cut a slot in the wall on both sides, feed the appropriate cables through and call it a day. This has since been discarded (see comment above ref better half!)
Plan B is to create a patch panel from a thin sheet of alminium, drill/dremmell out a few holes and affix the appropriate patch leads. This will be painted to match the wall, have a nice trim around it, and hidden under the desk. Same again will be mirrored on the opposite side of the wall to interface with the PC.
Question I have for the wise revolves around what connections I should be considering. At this stage, I'm thinking the following:
HDMI x 2 - Current PC is quite old (DVI outputs on GPU). I'm running two screens at the moment, which again are old, having only VGA and DVI inputs. I was thinking HDMI for future proofing and using adaptors between initially. Would I be better going for DP instead?
USB 3.0 x 4? - Allow for connection of periphials - although it might be easier to only bring one or two through the wall and use a hub on the office side perhaps?
RJ45 - going to run two data lines to the cupboard, might as well run three and bring one through the wall for ease of connecting anything temporaraliy
3.5mm audio - Speakers / headphones.
Have I missed anything or has anyone done something similar? More than happy to hear anyone's thoughts or advice.
