Coffee spillage---resolved I hope

Regrettably even after sufficient time, it will not fire up despite battery being close to 100%........Duh.
She is not an avid computer user but likes independence from my iMac, so she hasn't got any meaty data on the machine, mainly emails and letters so if that's lost so be it. Given the lack of important data, she had thought she didn't want to bother with an external HD back-up !
Have been lucky to acquire a newer Macbook though, so generally it's onwards and upwards.....family peace restored.
Have taken HD out of the former laptop but gather I need buy/borrow/have access to an "Enclosure" to enable transfer from old freestanding 2.5" SSD to the newer laptop ? It's really really not worth the hassle or expense or time doing much, and certainly not worth going to Apple or even a local computer shop.
Do I now smash the HD......... or would anybody at a meeting have the "kit" to achieve a data transfer before I do so?
