I have a couple older laptops but I shelved my 2013 15" rMBP a couple years ago when I got a 14" M2 rMBP. Haven't used it since.
I have a Powerbook 5300, 190, and 1400 that worked when I put them in the crate. And I think about 1 1/2 Wallstreet G3s worth of parts.
I have a 2009 chiclet Macbook, but it has no RAM or SSD. (I think I gave them to someone here, actually.)
When my brother died I "inherited" the pile of stuff he had in my dads basement, including a 14" iBook G4, an HP EliteBook, and an XBox 360. That's all still in the box because 1) It still smells like cigarettes, and 2) I still don't really want to go through it.
