I stopped by my local Lowe's to look for longer M3 screws and nuts for easy grounding, and they had very little to choose from. I found this place online with a large selection. Now it's back to the waiting game.
http://www.rcplanet.com/1x Axial Hex Socket Flat Head M3x12mm Black (10) AXIA146 $2.50
1x Thunder Tiger M3 Nut TTRPD1196 $1.79
2x HPI Flat Head Screw M4x12mm (10) HPI94530 $2.75
2x Integy Shim Washer M4 (1mm to 4mm) Assorted Thickness INTC23235 $6.95
(Note, M3 screws and nuts for grounding IEC and XLR's and longer M4 screws and washers in case I want to insert a space between the top and bottom of the case for additional air flow).
