So my kitchen in the house I'm buying is the same style of first photo (slightly more modern, but not much). I can't afford to fit a new one for a while so looking for affordable options in the meantime. Could these units be painted white? And I hate the built in extractor fan. Would it be simple to remove the built in one and have it like photo number 2? Haven't a clue how much this would cost, any ideas? And would it be a simple job as they seem to be all built together? TIA
