Electric, for 120gb of RAM, you would have to have an insanely large processor, motherboard, and tower all together. Your case itself would be about the size of a 2 seated sofa. And really, if you were getting lagged by message spam on a supposed "120gb RAM" computer, then your computer doesn't have 120gb RAM. It more or less has about 1gb of RAM, if you're being lagged by spam text, which is just a representation of pixels that form on the screen just like any other game, etc. Stop fucking lying and be a man about your system. I only have 3gb of RAM. Big whoop. It's cheap and gets the job done.
