@RunaVolkov - if the typical shounen reader is in middle/high school, a 32-yr-old dude is about twice the age 😳 That might well qualify as "old"
That said, as someone who is in his mid-40s, having an early 30s dude called "old" sure makes *me* feel old 😅
@Bakakura1 - probably an iMac G3, given that the casing is transparent/translucent
Could be any model from 1998 to 2003, excluding Flower Power and Blue Dalmatian of Feb 2001, and the Snow colour variant from 2000 to 2003
