fretters

I agree that it is a very detailed instructable and superbly illustrated, but surely a dough/pastry/pizza cutting wheel would work just as well?

The egg crates are there to stop the echo in the room. If you scroll down the comments, I have a better explanation and photos.

Very true. They are basic cheap cables, but they are only used for standard, everyday sound. I also have an M-audio sound card that runs through (semi) shielded cables into my Naim Audio set up for music.

Thanks, that was essential!

Yes, I'll try to share the TinkerCad file later. I wasn't aware that was possible before.

This works exceptionally well at keeping the electronics cool and totally free of dust. As I mentioned in a previous reply, I've been using the drawer for nearly a year now and there is barely a speck of dust inside the box. And the CPU never gets to anywhere near a dangerous temperature, and the fans are as close to silent as I can imagine.

The hard drives have been fine for nearly a year so far. Its not like I open and close it every day (although I did at first, just to look at it!). The drawer is closed most of the time and if I ever need to swap a drive, the computer is turned off.
