sys-r, sys-f, I'm getting sysed-off
I bought this the other day and was about to shelve it for a long while because I did not know what some of the terms were in the small piece of paper that are called instructions.
Could someone clarify what sys-r and sys-f are?  I'm guessing sys-f is the fan for the CPU, but what is sys-r?
I also am confused about the HDD wire.  Is that an option for replacing the case HDD?  Can I choose not to use it without something going wrong with the controller?
Thanks in advance for the help.  Am glad I found this forum.
