no, no soldering. Everything is push and play, and 99% of the thing can only go one way. The only somewhat hairy part is sticking the CPU in the motherboard without bending any pins (it goes one of 4 ways, and each CPU has about 1,000 little tiny assed brass pins in it) and then clamping down the heat sink without feeling like your going to break the chintzy assed plastic electrical boards in half. Other than that, it really is plug in play. Deciphering the chi-com instruction booklets and diagrams is a little bit entertaining sometimes, but it really is easy. Once you've built one you can go from a totally stripped pile of
parts and a case to a full built booting machine in probably 20 minutes, if even that.
Newegg and Tiger direct both are great to order from. I've bought from Newegg for like 10 years and never had nothing but excellent results with them.
Here is a video I haven't watched, but probably explains the whole thing for you
