Fridge removal / Mod

[Paddywackcocker]

Hello
I have a 44ac and won't to gain access to the fridge unit, eather to up insulation or fit a better unit.
I can't work out how to remove panels ?
There doesn't appear to have any obvious screws, there's fillets by the side but they seam stuck fast.
Does anybody know or done this
Regards
