Scrap that you collect or keep for yourself? - Page 2

I just realized today I'm starting to develop a small problem... I tend to want to keep some of the more interesting "scrap" I accumulate, mostly being EScrap related. Not a problem by itself, but it's starting to take up a decent chunk of valuable space! So it got me to thinking, what type of scrap do you guys like to keep for yourself? Collectibles? Investment grade items? Stuff that's just plain cool?
Goodies I tend to save up or keep :

Small high value EScrap, like processors, RAM, pins, fingers, etc... Doesn't really count, I suppose, since I do intend on selling it all at some point.
Fancy looking heatsinks, pretty much all solid copper heatsinks.
Cool looking circuit boards, due to design, color, usefulness, whatever.
Certain connectors and adapters, some because they're somewhat rare (even though I'll probably never use them) and I like to have 1 of each type regardless.
Anti static bags... I've been accumulating a lot of these lately, they're quite useful of course, but I know I'll never use ALL of them.
Software! I have so much software it's ridiculous.. I'll never ever use 99% of it, and 90% you can't even give away. But I just can't bear to throw it out... If it's burned/copied/whatever I have no problems, but for whatever reason I just can't throw out the legit ones.
Those "wheels" with the copper "spokes" you find in 3.5" floppy drives, I'm thinking Steampunk market?
Keyboards and ball mice! Not by choice, though Haven't decided if I want to bother getting the mylar... I'll probably just donate the whole lot of them.

I'll throw up a few pictures of my cooler stuff if there's much interest in the thread, so how about y'all? What are your hoardy quirks?
