Ps3 491 Top -

Based on the cryptic nature of the string "ps3 491 top," this most likely refers to a Sony PlayStation 3 (PS3) model, specifically a unit with the CECH-491 model number.

Here is a comprehensive paper (product profile) regarding the PlayStation 3 CECH-491.

Why the "Top" matters: The loading mechanism on these Dev Kits is notorious for breaking. The springs wear out, and the plastic hinge cracks. Thus, a "PS3 491 Top" in good condition (without cracks on the hinge mounts) is worth more than the console itself in some markets.
