I have a plan to put my pc in a cupboard on the opposite side of the wall from the office. Noise disappears, space in the office increases and SWMBO won't have to look at "that monstrosity".

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.

Thanks.
