I've got various old bits, although not too much as it tends to end up being passed on to family and friends.
Currently it includes an original Geforce card (I think it's an original GF, although it might be a GF2), some 72pin Edo ram that's been living in my spares box since before I retired the P166, a couple of RealMagic Hollywood+ DVD decoder cards (complete with pass-through cables), although they're now in my bedroom bin in their AS bags waiting for it to be emptied

2x Athlon thunderbird systems (I think one needs a new psu and hdd), an amd XP2400+ (I think it is) based system, a P700 system, and at least 2 additional cases cluttering up the place.
A few old Duron/Thunderbird processors (I think they range from a D650 to a Tbird Axia 1000).
An Asus P4P 800 motherboard (P4) i think.
Erm I think that's more than I had thought...
About the only bits out of that lot I want to keep are a couple of the cases (Globalwin 802's), and the 2400 as a spare system.
I may offer some of the bits in the MM for collection at some point in the near future, as I really need the space, but it's not really worth me sending the stuff through the post
