How much is this modded 60GB backwards compatible PS3 worth?

Hi there! I'm new in the forum and in the country and I'm impressed about how cheap are consoles here!

I'm very interested about playing PS2 videogames in PS3 and the 60 backward console is very hard to find in my country.

So my question is, how much is this modded 60GB backwards compatible PS3 worth?

Is the EZ Chill Fan Mod for PS3 safe? It will really prevent overheating? Any experiences, comments or recomendations?

I will really appreciate it! :)
