You are completely free in configuring the system you want to send in. This is YOUR responsibility and yes, we check this incognito. Please, don't wait until the very last minute to send in your system. The only cost for you is the transportation to and from Data Testlab.
Every system needs to be photographed.
If possible, put a printed copy of the questionnaire with the corresponding system you are about to send. The ones we provide here are the only valid ones. Print out the document, sign it and put it with the system.
