I would not mind in Spanish is: No me importaria.
The correct phrase would be 'she has an open mind' and the translation that Google have me was 'ella tiene una mente abierta'
Keep in mind that this is NOT a gramatically correct phrase anyway so it would be hard to translate so it made sense. You CAN say what you want to say in Spanish, I'm sure but it would have to be said differently.
en el mente
Da igual.
To say 'I have a microwave' in Spanish, you would say 'Tengo una microonda.'
To say 'I have a notebook' in Spanish, you would say 'Tengo un cuaderno.'
Normally you would say "estás loco". This indicates mood or state of mind, hopefully temporary. If you say "eres loco" it indicates an intrinsic, permanant characteristic.
To say 'furniture shop' in Spanish, you would say 'muebleria.'
este hombre esta loco!
Principalmente en mi mente
To say 'knives' in Spanish, you would say 'cuchillos.'
To say 'evaporation' in Spanish, you would say 'evaporación.'
