Remember - when making things to mount drives in -
junked PC cases are your friend. You can drill out
those rivets and have nice, pre-made drive frames. And
don't overlook that metal pipe-hanger strapping - the
metal strips with holes in them. Erector set pieces
work too.
I have quite a lot of blank, undrilled, aluminum rack panels in
various sizes and thicknesses.
