nOrh DIY Kits

Has anyone assembled a nOrh DIY kit? I'm looking at buying the 7.0 or mini 9.0 kit. It cuts the price by 2/3.

However, I have no experience in DIY electronics, and I haven't had any kind of physical science since 7th grade. Are these kits "doable" by inexperienced people? How much would the necessary tools cost?

Thanks, and Happy New Year!!!
