After testing several distros in an old PC I assembled in 2001 (15 years ago!), with different results, I was not completely satisfied.
I installed LXLE 16.04.1 and result is EXCELLENT: Web navigation, videos / sound playing, Office applications go smoothly, and even streaming video from youtube plays fine. Last but not least, distribution look and feel is very beautiful and pleasant to use.
I recovered this abandoned PC and now I will use it occasionally in my mother's home.
These are the PC specifications:
MS-6330 LE Motherboard / AMD Athlon 1133 Mhz CPU (32 bits / PAE) / 1280 MB RAM / 40 GB HD / Riva TNT2 PCI VGA Card / Realtek 8139 10/100 Eth Card
Congratulations to LXLE team. You have done a great work!
I hate to throw away my old PCs/NBs so I've used many light distros. LXLE is light, is quick and is the only one which I have never had problems of instability. ~stupenDOS
