You find out from some coworkers that you live within 5 kilometers of Akihabara Electric Town. Which is practically the best place in Tokyo to get PC parts.
Assuming you go there. You find a Mecca for Consumer Electronics, Anime, Manga and PCs. There are Maid Cafes here and there and Cosplayers everywhere.
Lita decides to go with you to shop. And seems to be fascinated by the cosplay and the Maid cafes and the anime pictures everywhere. She is also curious about the pc components that you bought.
You manage to get a cpu that would have been amazing in 2015 or 2016. But it is just above average here. You get a decent Motherboard that has an integrated GPU. And 8 GB of ram. Along with a case, Monitor, keyboard and mouse. All for under 70,000 yen. (About $700)
All from a out of the way shop in Akihabara
