Overall condition is fair, the lid and the bottom has scuffs.
For the cosmetic condition please check photos. 

The laptop has been tested under high load (Unigine Valley) at about 24 hrs - no issues

8GB RAM, 500GB HDD.
Diagnostics is ok. 

I wasn't able to test the battery, just unplugged a power adapter and checked how the battery lasts

No power adapter sorry, 
no returns
