looking for full cover (back and front, top, and bottom)

Hi @murtaza39315

Two options:

a). Search online for

Asus FX504 base enclosure,

Asus FX504 LCD back cover,

Asus FX504 LCD front bezel cover

Asus FX504 upper case + palm rest assembly

to find suppliers of the parts you require.

b). The Asus part number for each of the parts can be found on a sticker on the underside of each part. Search online for the Asus part number for the part (found on the sticker) to find suppliers that suit you best. Here's a teardown video that may help with the disassembly. e.g. at 17:33 minutes into the video you can see the sticker in the middle of the LCD back cover.
