Looking for KVM ...

Right now, I was crawling around Dialectstream, stumbled upon one simple, but certainly useful piece , but the existing connectors did not suit me there ...
Wildly I would like to see ports: video, 3.5 audio and 2 USB. All this on 2 computers, that is, 2 sets of input ports, and one set per output. Switches, maybe even better to be separate.
Accordingly, a little thought, and googling (at the same time, not finding anything intelligible), there was an idea to do this with his own hand ...

I would like to ask the public whether something like this has been realized somewhere?
If not, then please share links to resources where there is an opportunity to order various dad / mama ports and / or shemes of such switches (the switching method itself is interested, although there are already 2 ideas ...). Yes, I confess, he himself is not all that he could have rummaged, and at 2 o'clock in the morning from Saturday to Sunday, he doesn’t have a lot of shopping, there are 2 reasons for that. The first reason - all the same, knowing our marketing, ordering online components, I will win at a price at least 2 times :). The second reason is that Habr is visited by many of the smartest people, and this gives hope that the idea will be completed on the first attempt, with minimal costs and without too much hemorrhoids.

Thanks in advance to those who respond to the request, or push for a practical thought.

- PS: please do not kick especially, all the same personal blog, and there will be a question for a long time ...

UPD: I don’t understand why there was a minus without a comment, but oh well, thanks to the iTNitro and l0ser140 users, the problem is almost gone.
I will not change the text, let it be evidence of my temporary attack of forgetfulness / stupidity.
It remains only to choose a more suitable model ...
Of the requirements - video (unpretentious VGA), mouse, keyboard, audio (microphone is not necessary at all) and, what the D-Link KVM-22 model didn’t suit me, usb-input is highly desirable, and 2 is better than USB devices, other than the keyboard and mouse (for example, a flash drive).
Maybe someone has the experience of using such devices, I do not want to miss the quality.

Excuse me for not having a chance ...

UPD2: So far, I 've recorded Aten CS1734B model for myself. In terms of functionality, exactly what I’m looking for, but the price ... I’m not happy ... at least really take on the soldering iron ...
