Mac Mini (mid-2010) - replacement harddisk

[memyselfandi]

So I think the disk is probably on the way out on one of my mid-2010 Mac Minis (the ones which were the new form-factor but with built in optical drives unlike the later ones).

I don't have much need for local storage so a drop in capacity wouldn't be an issue (I think it's got a 320GB mechanical drive now) so does anyone have any recommendations on replacement drives?

Also is there a recommended online guide to replacing the drives in these (previously I've upgraded the memory but that was trivial where as this looks like it might be slightly more involved) ?

Thanks

So any, say, Samsung or Crucial SSD would be ok then?
