I used crucial. The ram is pretty straight forward, the ssd was a bit fiddlier but I still managed it despite zero electrical fiddling experience. Definitely consider the cost of all that though. Always up for keeping a device alive but there might be most cost effective options out there
Thanks all. @mrJL any suppliers for ram and ssd you’d recommend?
Assume there are guides online on how to do it but any obvious gotchas I should be aware of?
