Hi,

Excellent guide.

I have one of these, and i was thinking of opening it up.

Its sound output disappeared one day. Quite unexpectedly.

No reason that i could see. Couldn't find anything in the

settings to make it go again.

Finally i thought that maybe its 'sound card' had gotten

jogged, or maybe loose, and needed 're-seating'.

After reading through your article on the SX-280,

i now see that it has no 'sound card'.

It has 'on-board' sound facilities.

So for me that has pros and cons.

Pros, i dont need to look for a sound card to re-seat it.

Cons, i dont know what to do about my lost sound now.

As to updating the images, i think they are appropriately

dated to suit this model of PC.

Pre-Requisites ... Not quite sure what this refers to.

Maybe a phillips screwdriver is a prerequisite.

Maybe i missed something, but i dont see that newer pics

would help at all, but the poster is quite correct about

this guide, it is very good.

Regards, John :)

Fan closer to heat sink

No need to remove rubber grommets. After pressing blue tap, fan can be moved sideways, towards housing, after about 2 to 3 mmm travel the slots that hold it become wider, and fan, plus blue plastic bracket can be lifted out.

Same is true for other fan, but more difficult to slide. This fan does not have

to be removed to get motherboard out.

Great guide! I got stuck at the Mobo tray, I knew the black screws were involved but couldn't get it with out help. Thanks!

Fans can be removed with board tray, otherwise they're getting pulled off their rubber isolating feet. Once out with the mobo, the fans slide off the board tray with their plastic shoes attached.
