Huh? Oblong pizzas?? :> (sorry, I just can't picture this :< )
I've "standardized" on "Vacutainer" boxes (vacutainers are those vacuum-filled, rubber-stoppered, "test tubes" that are used when blood is drawn). They are ~18x12x6 so they fit nicely on my (18 inch deep) shelves. They are big enough that I can store "enough" in each -- yet not *too* big to end up with lots of "empty space".
E.g., I have a box for SCSI "1" cables, "2", "wide", VHDCI, DB25, VGA, DVI, 10Base2, "RJ45", etc.; boxes for screwdrivers, chisels, drills, etc.; CD-ROMs, DVD writers, speech synthesizers, barcode readers, PDAs, signature pads, etc.; development boards (SBC's), hookup wire scraps, etc.; access points, routers, network fabric, network appliances, etc.
[I think there are ~130 of these boxes currently]
I like the cables sorted. Probably 25% of my "storage" is dedicated to cables. I suspect there is more *real* "value" there than in any of the other stuff -- it seems like I don't go more than a day without needing to dig out some sort of cable! Especially all of the odd-ball "specials" common for USB :-/
I don't throw *out* anything. Everything gets recycled.
I don't save "old" stuff anymore -- unless I need it to support an old design, etc. E.g., I have only one ISA bus PC -- but, it can support two *full* length cards.
OTOH, I got bit yesterday as I needed a PS2 keyboard and didn't have a "spare" (I only keep a few spare keyboards and most of those are "specials") so I had to borrow one from one of my servers. :<
I really like these little *tiny* keyboards (about 12" wide?) for those machines that I run headless -- yet "need" a keyboard to be able to power it down "locally" (i.e., "typing blind").
[I keep a portable *7* inch LCD monitor for those times when I need to connect a display to a headless machine... requires a bit of squinting to read but a lot nicer than having to lug a larger monitor around!]
