Best way to source the part is to enter your product code into the search at partsurfer.hp.com which will give you the most up to date list of available parts. that said, these are pretty universal and you can likely pickup a drive here https://www.ebay.ca/itm/145200958237?itmmeta=01HYKNB35SYV819ZC45G12SPSY&hash=item21cea6cb1d:g:r0IAAO...

that will work fine. The faceplate might be slightly different but 9.5mm drives are pretty standard. HP does not list the faceplate bezel separately in the Maintenance guide here: https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=http://h10032.www1.hp.com/ctg/Manu...

Comes with the face plate and green bracket.

The parts list for a random 800 G5 SFF indicates you need a 6" SATA data cable:
