I am planning to use an old mini at tower case which I have gutted. Gives me plenty of room to mount M10000 board plus 300watt ATX power suppy and all peripherals.The inverter is the only item which will not be enclosed in the case. This will all be placed in the boot of which there is plenty of room.As I already have an amp mounted in the boot can anybody see a problem hardwiring the inverter using the power wire already fused at the battery under the bonnet in the front 8 inches from the terminal.Will I need to fuse the inverter (300watt) again(already has built in fuse).Anything else to look out for.
