Kalniel,
I massively appreciate those links but, for sure (judging by the pics, anyway) some of those cards are definitely not half-height - and I think they include
your recommended card - though it's very hard to tell.
And I say this while realising that with those that do look suitable, it will be necessary for me to remove the existing backplate (and throw away the VGA connector) and substitute a low-profile backplate.
Fortunately, I can use the backplate from the duff card - something I realised in the early hours of the morning when I also discovered that I already had one of
these, cheap and nasty jobbies - and managed easily enough to get it installed and running with original card's low-profile backplate.
