Hi Primogen!
There were a few places I could have bought from but to save time and petrol money I went and bought it at builders warehouse up the road from me. They can cut to the exact dimensions plus if you go in the morning your wood will be ready for collection in the afternoon. They also stocked most of the different colors of melamine available these days.
But I do suggest you phone around a little bit, you may be able to get it cheaper. Builders warehouse charged me around R730 for one sheet including the cut up.
Funny enough, there was another place I initially went to as it's basically walking distance from where I stay. They wanted to charge R900 odd plus it would have taken them a week to cut it up for me. So best you call around, I'm sure you can score a deal somewhere.
And now it's finally official! I cannot get these rails anywhere. My only hope was builders warehouse for 6mm brown rails, altogether setting me back R540. Not to mention, the glass was nearly half this price. Price is cr@p and 6mm is too big.
Cabinet is now standing, I have everything sorted out. Vent holes with vent covers, light holes, light setups, sealed the whole cabinet. So now the cabinet is standing looking so beautiful half naked with the glass sitting next to it
