No it's not a saphire, too lazy to reopen it again. But it looks exactly like this model with some minor difference like color of the board. The choke coils aren't sealed (only the top one is).
The exact model is HD587X-ZNFC (not ZNFV; that board is adaptable easily to the accelero). It's a XFX
I am currently searching for some tim pad and once I find some, I'll post some new fresh pictures with my new mods. Until that, if you have any idea or suggestion let me know!
