Birthday Present For My Mother

Two months ago, I forgot to prepare my mother's birthday present.

And after one month from now, I will go back to my hometown for some reason.

Since I want to give my mother a present at that time, I bought a SSD today.

Of course, my mother doesn't want such a SSD, but she previously said "I wish I could have had my laptop.."

Therefore, I decided to compose a laptop using my old PC components and the SSD.

I'm sure she likes this laptop! :D
