I'm getting a 'Ferrari Red' Cosmos tomorrow (for £50!) and because the Tubby Custard Machine (named after the pink coolant mix I use) needs a bigger home (can't fit my Meanwell clone TEC PSU), the red goes nicely with the sofas in our living room, the wife approves and gave me the retro idea and a Cosmos 1000 for £50 is a bargain.

I'm planning to do a Retro-Futurist make over incorporating analogue dials, shiny polished copper cooling pipes with glass view ports, blood red fluid.

One major mod I plan to do to the case is to cut access holes in the motherboard tray behind ti CPU, VRMs, Northbridge & Southbridge. Will this have a negative impact on EMI (received or transmitted) or structural integritty?
