Update 3-11-2017
I finally managed to get around to building the keyboard tray. And the first version... well... it failed. But, I will show the pictures anyway:
I started with an old, under-desk style of keyboard tray, that I took off an old desk, out at my local dump/last chance yard.
I removed the mount from the tray, as the tray was actually, about a half an inch too wide! So, I began to make my own tray instead.
I then, mounted the rail onto the case:
However, upon first use of the tray, I found that the tray was too far back and would not tuck away properly. So, I made an extension:
At this point, the keyboard tucked away nicely:
But then! Then, I ran into the next issue... how and where to attach my mouse pad? Crap... It was at this point (and 12:30 in the morning, by the way) that I realized that this particular design would not work. So... I re-thunk it.
I took the old the tray, that I was going to toss out, and modified it to fit with the confines of the case. I wasn't about to let that half an inch deter me!
So... I cut off 4 inches! And this is the result!
It works pretty well, now! I have plenty of room on the mousepad for movement and plenty of space for the keyboard, as well. It tucks into the front nicely, too.
I managed to fix my fan wiring this morning, too. I found out that I had miss-mired the CAT5 connector that I was using in the door, which caused me to create the magic, blue smoke from my fan controller... so now... I'll need a new controller. But otherwise, that cabling is working properly now.
Next up will the be integration of the subwoofer and speaker inputs, into the floor board. Then, put in the last of the door connections so that the doors will be easily removable, when necessary.
Thanks!
