Below is the current build I am thinking of buying, but I need some suggestions and help.
Should I be getting a wired or wireless adapter?
Are there enough fans? Where should I position these fans?
What PSU could you recommend?
Do I need an optical drive?
And finally, what case should I get?

Thanks in advance to those who give suggestions and answer questions!
