I've got the time, just not really the spare money, if I could just go to the stockist in person I would happily get 2 fresh sheets as it would only be £16 the £10 postage is good when ordering a lot, but just 2 sheets, I over ordered with the bars just wish I did with the sheets, but this is my v2 and want it to look good and be my final cube case before doing something different so I think yes I will order them tomorrow, at least the sheets that will be coming out of this project will come in handy for other something else some time, its always good to have some scrap.
The tray I used for aligning the holes was from a cheap atx case, the back expansion I/O piece is from the last case I bought, a Lian-Li PC-A70A, I mounted an old motherboard on the tray I made last night and the standoffs I bought off ebay are taller than regular ones so the back panel is too low and does not line up correctly so I need to order some normal standoffs.
Wow and duh I just got an idea, the side panels have not been cut down to size yet so I can just cut the bottom bit down, again blue you stirred a good idea for me by making me think about it TY .
