still seeking advice

Party On,

Here is some food for thought. One of the most time consuming jobs when setting up at a gig is stringing cables and wires, at least for me it is. The PC you are having built sounds like a desk top model. Why not use a laptop computer? With a desktop computer you are going to have the CPU, keyboard, monitor, and mouse, all requiring a hook up. Do you really want to cart around these seperate components?

Powered speakers are heavy and require an additional power cord. Will power be conveniently available or will you have to string an extension cable? The speakers will probably sit on a speaker stand. How high can you lift a powered speaker by yourself?

The audio output from a computer, be it laptop or desktop, will be sufficient to drive a mixer.

The software you use for DJ music is really up to you, there is no one program that is better than any other. For everyone that responds to your post you will get a different answer. I like OtsDJ.

Just my 2 cents
