Alternative enclosure / casing?

[ThinkPad]

Is anyone using an alternative enclosure / casing for the OTGW? I find the suggested casing (this one) very annoying when you have to open it, those pins are a pain in the *** to 'unlock'

If i understand the datasheet of the enclosure correctly, the mounting stands are
84,6mm (longest side) and 55,7mm (short side) apart from eachother.

I could start searching the whole Conrad.nl site, but maybe someone has already used an other casing with success?
