Coming on a journey with me of completely over engineering the sh*t out of a media cabinet

Disclaimer: it’s not a CNC project I just was 3d printing these parts because in this case it was way easier and streamline for me as well a kind of look I wanted to achieve but of course anything could have been cnc`ed.

So let me start… In Germany were havin internet provided over the “cable TV line” and these cables happen to come out in my living room of course because that’s the regular place where your Tv is living at.

Rerouting cables in Germany is not so an easy task because everything is concrete or brick so I had to come up with a solution putting my internet/TV/console/smarthome stuff in a room where we are mostly living in and hide it.

The problem of hiding electronic of any kind ist that this stuff doesn’t like closed spaces and or heat… And of course I’m an Mechatronic engineer and like to over do stuff for the sake of having it done and feeling all warm And fuzzy inside :sweat_smile:. On top of that comes the requests of my wife no visible stuff or open cabinets or diffusing materials like waved rattan or slatted wood what so ever clean and streamline it should be like the rest of our furniture white and oak.

That’s what I’m dealing with as a base line.

I put up this cabinet as an version 1 as we moved in and didn’t took much time designing or building that as well as had several changes within my smart home system. And now I want to upgrade to V2 because the old one is too loud too messy and I got happy and get my hands on a Ps5 and I have the fear it’s going to overheat in there.

How is v1 looking what’s it from. So v1 are method cabinets from Ikea, floating mounted on the wall with 3d printed inserts and 120mm fans to provide a fresh breeze. Everything controlled by a pc fan speed controller and temp sensors for the devices buttond up with an oak counter top as shell.

So now that I wrote a half side in a gallery blog that’s the pics o v1:

My in depth problems with V1:

  1. Noise…got around 35db of noise on the outside of the cabinet in running condition so when the TV is turned on and all network running.

  2. the cable management is a mess

  3. the joinery on the top plate is bugging me… because its just a but joint

  4. i got a ps5 and have to put it inside the small cabinet and the exhaust is on the back and there is mostly no circulating air.

  5. fans a pushing fresh air in, no dedicated outlet of any kind, general position of the fans on the bottom and not on the back where most generated heat is pushed.

  6. too many fans… a bit over over powered, the box around 0,122m³ and one fan on full blast is rated with 48 cfm so 192 cfm on full blast fans running quite low lets say 80 cfm that is then: 80 Cubic foot per minute [cfm] = 135,92 Kubikmeter per hour [m³/h] and yeah even with back pressure from missing outlets and so on you get my point.

these are my main headache points and all i want to change in V2. stay with me its getting more and more bonkers

3d model for V2:

  1. things that didnt changed, im still using the Method cabinets because my wife really liked the look of it, so i designed my stuff around it.

  2. Blower fans on the back side, double isolated and damped for silence sucking air out from the highest point and on the back of the devices

  3. way less fans ((7) in total 2 running permanent 1 per cabinet for ambient control and the rest for the ps5 so i can play with doors closed) rated with around 35 cfm full blast each. dedicated temperature control with a bought solution from ac infinity. I wouldnt describe this as an update of any kind its more of a declutter and they have these nice silent 5V blower fans with 120mm that i didnt found cheaper or more silent and i wanted to extrude air from the back so i dont block them with devices standing on top.

  4. dedicated air inlet

  5. better cable management easier to restructure the smart home with an ikea pegboard as divider wall and magnet holders for easy cable access

  6. one larger cabinet to fit in the PS5 better because that boi is memeish large…

Interesting project!

One observation is that the acoustic foam is probably pointless in this scenario since the cabinet will act as a resonator with all those vibrating things inside it. The foam is also a thermal insulator.

Jep completly true, had some laying around and put it in v1.

V2 has all fans floating and damped against the cabinet so no direct surtdy connection is made up that can hand over the vibrations

Good to see you back here! I have always admired the quality of your work!

Thank you very much. That really means quite much too me.

was never far away always listening and reading in the shadows, Liking stuff​:sweat_smile:. But my CNC is working flawlessly and I don’t make such amazing or exiting projects as all of you do. So creeping up from time to time :blush:

That’s very cool, I’ve never seen a floating cabinet like that but it makes sense, the kitchen cabinets are screwed to the wall.

Great inside design too!

Builded the two 80cm wide cabinets and cut the air inlets with my plunge cut saw as well as cut the new plywood back walls to size and partially assembled them. Then I quickly test fitted the fan grills and duct.
(I made some 3d printed drill guides and spacer so building and fit worked like a charm and to my personal suprise I had no tear out…)

Things ahead:

  • Mount the pegboard magnet holders
  • Cut and mount the pegboard
  • Find a perfect spot for the cable pass through of the fans
  • Pre mount the AC infinity display
  • Dampening the back side of the plywood and then assemble fans and ducts
  • Pre wiring and wire management with cable channels
