I heard of Sagers back when Alienware used them, at the time looking at Alienware laptops, I look a little deeper to figure out who the ODM was, and bought a Sager 5660 at that time :P
The 5660 which is now my Dad's computer still runs strong to this day.
2.4 P4 256MB RAM 40 Gig 5400 RPM HDD Radeon 9000 64MB
Then I bought a 5670 (thought that extra 64MB of VRam was worth it!)
Sold That to a friend who needed a powerful laptop for work... Same specs as the one above only with 128MB VRam
Then Bougth a 5680 when they first came up....
Was one of the first orders on it... Had it for a long while till I felt the urge for a desktop again..... Sold that to a member of the Forums here...
Desktop didn't even see the light of day before I bought a 4780!
My favorite of all the Sagers! Downside... Heat... and Size wasn't best for portability.... Also Sold to the Same person on the forums here that bought my 5680 :P (we have a long lasting trading / business relationship!)
Now looking at Sager 5690 or possibly a Dell 9100
Sadly my budget is only around $1500 right now
