amypme got backside images of a 4870??

i want to verify wether i can reuse a full cover block on these cards (maybe i'll go for FC blocks for my 3870s) and take a look at the vrm mounting holes + memory chip placement (so i far i know that a watercool hk gpu-x² could fit if the 4870 makes use of the same vrm as the 3870s (4850 has the same as 3850...)
