since i'm not allowed to comment on anything else i have. i have commented here. also not being able to comment and vote for and comment everything is stupid. not listing everything is stupid, too. especially when you look it up in builds and it doesn't show up. you gotta hack and input it manually. what is this? some kind of conpsiracy to only promote certain popular desktop computer parts? how bias... since there isn't a bbs forum, and i don't really have anything else i can comment on, i'll just post this all here. anyway. i like the 1TB. 10/10. would buy again. if i had any money. i like the 2TB too. but it's too expensive at $1000. too expensive now at $800 too. maybe when it's at $600 to $400 or something.
