It is probably best to put the individual items in a separate table
and link their keys, as an example with 3 tables

table items
itemid
name

table item_list
pcid
itemid

table pc
pcid
location


then these could contain
items
itemid  name
1       memory module
2       floppy drive

pc
pcid location
1    reception

item_list
pcid itemid
1    1
1    1
1    2

so reception pc contains 2 memory modules and 1 floppy

Hope that helps
