Well youliang thanks for the feedback. and thanks for the advise. im still new on checking background of sellers. i mean after hours/days/weeks or checking on the pc parts like compatibility or not and etc. the seller part seems to make my head swim also. but do u have any suggestions how do we do a background check on sellers here? or we should just come in the dispute thread and type the name and see if any dispute turn out? I will have to be more careful next time and i will also do my best to warn ppl so that others like u and me will not end up with this predicament.
