Looks good, let us know how you get on with the gaming temps.
I've decided on the cooling solution for mine. Going to piggy-back on some very good research performed by M1AF on the SFFPC subReddit and go with a 92mm Chromax rear intake. Alongside that, a 120mm Chromax under the C14S and 2x120mm (15mm) Chromax fans on the side, all pushing air towards the side panel.
I'm iGPU-bound for a while (£) but will probably end up going for an open fan GPU and 2 x 120mm Chromax fans as exhausts on the floor of the case. Having measured it up, could also potentially add another 92mm Chromax slim under the PSU position as an intake but would probably be overkill and be mostly blocked by PSU cables anyway.
Was tempting to put the PSU to the front of the case and go with a full 140mm fan under the C14S as it is intended to have but you lose the front-most fan support on the side panel bracket if you go with that orientation. Long-term plan would be to replace the 120mm under the C14S with a 140mm Chromax (15mm) when/if it comes to market.
In terms of scratch-ability, I can't say I noticed anything particularly bad although if you look at a few people's pictures of the screw holes that go into the rear of the case (to support the side fan bracket), they do tend to be quite badly worn after a bit of use.
