CB400 1979: is this a good bike for a starter?

Hello all,pretty new here so I'm sorry if this question has been asked before :)I'm looking to build a caferacer although I have 0 experience and very (very!) little knowledge of how to (re)build a motorcycle. Currently I'm looking at this CB400 from 1979 and was wondering if this is a decent bike to start a project with.​The bike itself runs although not very smoothly, has around 30K miles and the seller would like to get around $600-$650 for it.Here are some pictures of the bike, if you're interested: picture - another picture - last picture.​Thank you in advance for helping this n00b out :) via /r/CafeRacers https://www.reddit.com/r/CafeRacers/comments/bhj6wo/cb400_1979_is_this_a_good_bike_for_a_starter/?utm_source=ifttt
