A week ago i somehow managed to buy fully working HP Proliant DL360 G7 with 2x Xeon X5660 and 48GB RAM for 5 euro, and now i dont know what OS to install, because Windows Server 2012 R2 (which i already installed) dont have enough important drivers to work correctly (like ATI ES1000 driver), about Windows Server 2008 R2 i am unsure, and i havent any experience with Linux server operating systems. What is the best system now for that old server?
when I tried to install Debian on hp dl360 g7 with gui, some errors appeared after the login window. but the gui started and worked on proxmox(but extremely slow)
