help me,how to mod gf mx440 card

[topeak]

i want to mod the low-pass filter(here is some comments, http://www.anandtech.com/showdoc.html?i=1577&p=5) ,but don't know how to do with it.
and i also google some instructions which don't need to remove the low-pass filters(http://www.techimo.com/forum/archive/index.php/t-10313.html).
"All you have to do is use a No.2 pencil and shade over the INDUCTORS ( which look like normal SMD(Surface Mount Devices) components but are labeled "L" and a number, such as 'L105' "

how can i do with the low-pass filter?
here is some snapshots of gf mx440 card,
