Of course, its not like you can just run to the store and buy those parts, they are very rare, no one makes them anymore. Take for instance RDRAM RamBus RIMM memory, no one carries that in stock. When would you need it? Well you probably wont EVER, but you never know when that homeless guy down on 5th Ave is gonna find a PC that needs RDRAM, and you will be prepared. So keep all that outdated stuff so you can do a good deed someday.
