Såsen builds bikes slow and dies whenever

OK, plans for this is as follows

Chorus/centaur 10 speed mixed groupset
Ugly 1"->1 1/8 converter from Decathlon
Nitto b135 bars
Thomson 90mm stem silver
GB or Honjo mudgurads
Sadle will be a Brooks with the post that came with. If I find a suiting Chorus Aero-post I'll replace the one that came with
Pelago porteur rack size large

Wheelset
I got a cheap Khasim wheelset of Ebay as a placeholder but the plan is to:

1. Get wheel building stand
   
2. Build a pair of silver 30mmish deep wheels with ca 28 spokes and dynamo in the front. Preferably TL-rims so that I can use the GP 5000 TLs that fucked up my thumb (placeholder wheels will have Marathons as to avoid any if possible likes on Insta).
   If anyone has a good recipe for an above wheelset, please chip in or else it's probably going to be a23-rims with whatever hubs I can find at a good price.
