I'd don't know. It's years ago. I look through the clear side wall and it looks like a big fan on a round heatsink. The fan has an intel sticker on it. The case has got fans all over it.
I can tell you this though. I think I asked him to install an SSD too, back everything up and reformat etc. Anyway he (this older Asian dude) rings me and says "What about the files?"
"What files?"
"The pictures and movies"
"Yah back it all up"
"What about the picturesand movies of the umm.. cough cough intimidate content"
"Yah back all that up too. What don't you have a porn collection? Please back that up too"
WTF?
