Looking good. Took me a while to work out the pics and then it clicked that the M/B is lying face up and it's windowed both sides. Very nice but a pain to make look tidy - nowhere to hide! You seem to have done well on that front with the exception of the PCIE power to the GPU. Could you - probably with braided extensions - run those either
- up the corner of the case, across the roof corner and then down to the card or
- up from the PSU as they are now but then up the other side of the gfx card and then bend nicely round to the top.
Wouldn't run straight across the window then. Just a thought....depends if you can be bothered really
