HP 852175-001 top cover is a replacement top panel for the HP 260 G2 Desktop Mini. It is identified in the parts listing as “Top cover” for this specific desktop model, making it suitable for restoring the upper cover when that part needs replacement.
The listing associates the part with the PP2, DM, ENTL configuration. This is the upper cover; the same listing identifies the lower cover separately as HP 852177-001, so the two part numbers refer to different panels.
