I have a six year old Sager laptop that is still running. They do run hot but not the hottest desktop replacement I've owned. Build quality was great but that was six years ago when they were building off those massive Clevo chassis. The only thing that ever went seriously wrong with it was the hinges breaking three years in and past warranty. I know they redesigned their hinge since then. Those Clevo chassis were great, you could upgrade and repair your own laptop quickly with ease.

The new Sagers are all thin and lite which makes me worry about heat but people say it's all right. They are also ugly as a top price Nike running shoe but not near the ugliest desktop replacments around (six years ago they offered plain brushed aluminium, understated and classy by comparison).

Support was great the few times I used it.

If they are as good as they used to be than they are very nice desktop replacments. The only company I can think of that will unambiguously offer better quality is Falcon NW, but omfg are they expensive. Falcon is in a class by itself, true laptop pornography.

You have to clean the dust out often to manage the heat on my older model. Opening it up for cleaning is a breeze but it is a small hassle.
