So i just picked up a 27" iMac and I have some Ram just setting here from my 2011 21'5 iMac that I just sold and I wanted to install it on the new 27" but I plan on returning it for the new ones if they release next month. Do you guys think I should install it and then remove them when I return the iMac? Would there be any issues? I'm almost 90% sure there wont be but still wanted to hear your thoughts on this. Thanks for the help in advance.
