I know that I had to take a look at my aunt's HP mini limited edition thing 110 or something (if was a free gift from StarHub internt when they had a promotion and thus the colour was predetermined) and I turned it on to find a lot of adware, ask toolbars and junk like that.
Then before that, I took a look at my girlfriend's Toshiba of some kind with even more adware and garbage which I also cleared. She now uses a dell xps 13 but I haven't gotten to looking at it since I've been busy
Worse still, I remember my cousin's "DGT" custom built PC years ago that not only had adware and garbage on it, but also a counterfeit windows XP pro, viruses and dust. I did later get hold of it when he upgraded to a HP dc5100 minitower and he now uses a ThinkPad X1 Carbon with a Singapore air force sticker on the lid...
As for that DGT PC, I did transfer it to a new case, then used it for a while for a variety of tasks, then the IDE controller on the board(a Biostar U8668 pro) died and I sold the board with processor and stock cooler to someone else, then the parts went various places and needless to say, it's long gone. It did have a Pentium 4 2GHz, 320 MB RAM (PC133), and a 40GB Maxtor hard drive.
