my brother is wanting me to build a system for him. he is going to use it for audio editing and video editing for his band. he also will be playing game on it. ive never built a computer for editing and was wondering what i can put together for him with a $1500 price limit. this will include everything like monitor, computer case and everything inside, speakers(most likely 2.1 speakers) and so forth. basically the computer itself will have to be under $1100 because he has to buy a monitor and speakers. any ideas/suggestions would be very appreciated.
