I have a Seaboard GR02. Been meaning to write up a longer review, but haven't got around to it yet.
In short, I'm happy with it. The main problem I had when building it was the non-standard front brake caliper mounting position. It's offset by 20mm, so set your flat mount adapter to 140mm for a 160mm disc. And if you have a 160mm-only caliper (Juin Tech), you'll need a 180mm disc - which the fork is rated for. Internal cable routing is only in the downtube and in the left fork 'leg', which makes it easy to cable - a feature in my book.
Got a size 50cm frame, which fits me well with a 110mm stem and short 70mm reach handlebars, I'm 174cm. Most bike brand size guides place me on a size M, but I'm more comfortable on smaller frames (S or S/M). I'm not all that flexible though, and I prefer a somewhat upright position.
Paintwork looks good to my untrained eyes, I have the Pearl White one. The only paint overspray was on the rear rack mounting points.
