So, as someone who works in IT, and is also a Land Rover owner, I reckon to have all the necessary qualifications (and collections of strange gadgets) to claim professional hoarding status.
I have, of course, boxes of ISA cards, including SCSI interfaces, ATA Raid cards, 3com network cards (by the hundred) old PCI cards, AGP graphics cards, broken keyboards and mice, ATA hard drives from 40MB capacity upwards - yes you read that right, 40MB Hard drives... loads of PC cases, including an original IBM XT, an original IBM AT, and an IBM PS2, a Sharp MZ80K, a couple of TRS80 and a Video-Genie, a Camputers Lynx, and some ZX81s.
BUT, I also have a replacement Series 3 rear-quarter chassis, a Ninety front axle casing, a pair of swivels from a Discovery 300Tdi, an R380 gearbox with a broken layshaft, a complete and intact LT230 transfer box, at least 2 pairs of halfshafts, a couple of propshafts, a set of 5 steel wheels, a 2.25 Petrol cylinder head, a complete but scattered around in bits Rover V8, so cylinder heads, sump, block, pistons, camshafts, crankshaft, tappets, rockers, pushrods, and all the other ancillaries, A Smiths heater, a set of Series2A dashboard instruments, a Series3 instrument binnacle, A Series3 seatbox, a set of Discovery 300Tdi sills, inner and outer, and door pillars, A and B, One Series2A R/H front wing, quite a few rusty outriggers, and a dismantled truckcab roof.
Then, I have a welder, a compressor and a full set of air tools, and hundreds of sets, partial sets, and mostly lost sets of sockets, allen keys, torx wrenches and individual tools. Whenever I go the find a 1/2 inch spanner and can't, I buy another one, same with 13mm spanners. I recently bought a 1/2 inch socket drive which you could use in confined spaces by twisting the handle, which I thought was cool.
As too finding the actual bit of Land Rover, or particular tool, when I want it... HA, no chance...
