Still rocking Dell Precision M4400 from 2009 with Intel Core 2 Duo and NVIDIA Quadro FX 770M. Arch + XFCE + Nvidia drivers from the AUR (not in main repos anymore). On my 5th battery pack and 3rd wifi module. Runs like a champ. Replaced CD drive with second SSD (replaced original HDD to SSD long ago). This laptop was powered on pretty much non-stop for 13 years! Dat thermal paste gotta be cooked solid by now. They just don't make 'em this good anymore...
