the bottom is as good as finished,
just need to order a flat pump with top...
if a Koolanc PMP-400 pump with top is maximum 40mm heigh.
I can take the bottom out any time it's a tight fit and is on 2 alu plates, nice and steady.
The usb internal, sata and ECP connector on the mobo is nice clean now.
This is no metal plate but 4mm not shiny black acryl plate PMMA15
only needs to get connectors for the PciE powercables for the GPU's :
