Thanks for your comments.
In terms of the depth, I went for this because I wanted to keep the cabinet slim. There will be significant weight on the back of the cabinet from the computer (as it will be mounted at the back) and the subwoofer. The LCD (yes, you guessed right
) will also be angled slightly back giving a little more weight to the back.
I also plan on using rail castors. The joy of these are that I can angle the machine slightly backwards by adjusting the front ones height to be a little more. It won't be noticeable but will make a difference.
In terms of height. I feel that a good height for me is 965mm. I put 1000mm height as the CP will be angled down by 30mm so the CP edge will be approx 970mm of the ground (slightly less as the CP edge will continue past the Box that hides all components, prob around 968mm). I tried 900mm on a box and I felt like a had to lean over the CP. I am aiming to keep my back fairly straight. I am also 6 foot, but my bro is 6' 1" and my dad is 5' 11" so I put the height that would be good for me as I am in the middle (and it is my cab! lol).
Here are the redrafted plans.
Franco, if you need anything just drop me line. Thanks again!
