Bleach: Is that an iMac G5?
Apparently there is one person at Studio Pierrot is an Apple fan. In one of Bleach (anime) episodes, an all in one computer sans logo is making an appearance. It looks pretty much identical with Apple iMac G5. The screen capture is taken from Bleach Anime episode 214.
Take a look at the back of an iMac G5 below and compare it to the first picture above.
It is pretty obvious that the computer in the episode is indeed modeled after the iMac G5.
Check out another screen capture from the same episode below.
