I'm guessing the top panel doesn't come with the control board, so I'd have to get the USB3 board as well. Meh.
If the Lite is around for £60 then might as well get one for the parts I need and flog the rest off as spares. I'll make do and mend for the moment, then look after Christmas. I like the case, only recently fitted the H100 to it. It fell about 4 foot, amazed the top of the front panel took the brunt of it and the main structure of the case is unaffected.
