Ok, cut the holes out from the case. Leaving the on/off switches, volume control buttons until later when work out their best positions - ie when the cart slot holder is in place, which is the next job.
Soon be at the stage to get this with a final sand and then paint. Cutting all these holes took a while; it will be interesting to see how long I take making a second case, obviously this first one takes the longest, I want to make a template to save time for future ones and maybe halve the preparation time with any luck.

I will document this work on my second case in a different and easy to follow format, this thread is on-going progress after all, as it happens and without too much structure.
Good progress in a short time:
Used a reject case top to form a template which I can then make future cases, so I know where to cut the holes / mark them out for people.

Previously, i've spent literally days on spray painting, getting a bit of a spit from the canister and having to re-sand yet again, finding some parts need about 1/4mm filling so having to prepare the hole thing, allowing hours before coats, etc, etc. Then when you think it's perfect, finding a small imperfection, trying to resolve it and most of the time making more work as a result.
NO MORE! This time i've used a mini paint roller with wall paint (after sanding the casing of course to roughen the surface for the paint to adhere), and got a really good result just from one coat; and fast, the entire case was painted in about 2 minutes. Need to apply one more coat certainly, maybe two as max more, will then varnish. The effect from a roller isn't perfectly smooth of course however gives a light texture which not only looks nice but also hides any tiny imperfections there may be really effectively.
Pic after one coat:

Went to B&Q this morning and got a medium sized tin of this paint for half price, so enough to paint many cases with it - i'll be the default colour for people and painted for no extra charge, if the buyer wants the case painted, as long as it's this colour. The colour is a beige, so neutral, will look nice against the black surround when that is spray painted a deep black.
Have three coats of paint on the case now, looks very nice. Trick is to keep a small amount of paint on the roller once the roller has taken all the paint it can; if you have a surplus of paint on the roller then the roller doesn't roll, so you need enough for new paint to be applied and also the roller to roll; that also gives a nice ripple effect on your case.
Assuming my old pot of paint varnish is still ok, going to use that instead of spray paint varnish; it gives a really tough finish to paint. I'm also going to spray paint the screen front section so that is ready when I need it. With a fair wind, i'm hoping tomorrow to be able to handle the case, remove any surplus paint from the button holes, complete the buttons and install them and also secure the black screen section to the case front. After that, need to install the shoulder buttons and then start work on the case backing.
Ok, back of case is painted and varnished. Front of case is painted and varnished, and dry. Buttons have been completed, set onto a slightly larger piece at the back to keep them in place inside the casing. The black screen front section is painted and varnished as are the shoulder buttons.

Tomorrow will start assembly.
