no matter how good you are at rebuilding stuff and finding stuff in 100% mint condition, it will never be like a factory built oem ITR. and if you got an ITr shell, chances are it was a stolen recovery or crashed, which means that that title isn't clear-- and well, there goes allt he value in the first place.
