Apple MacBook Pro 16" (1TB SSD, Intel Core i9 9th Gen., 2.30 GHz, 16GB) Laptop. I bought this brand new just before lockdown in 2020 (and I have been the sole owner) in the hopes I would be motivated to teach myself to code. Plot twist: I did not learn to code. This poor machine did not get to live out its potential, it has instead been used as a glorified and very expensive YouTube machine. Selling now as I am raising funds to build myself a gaming PC instead. It is in excellent condition apart from the patterns you can see on the bottom of the machine. I have had the laptop in a case for years so was unaware it has marked the bottom of the machine. Pic of the case is the last picture so you can see where the grate style markings have come from.
