As for the operating system, as my desktop PC and still I have not migrated to Debian, I will use Ubuntu Desktop. Although if the PC that you have only to be used as a server I recommend a distribution Server without graphical interface, especially if your PC to do this is a P4.
Kama kwa mfumo wa uendeshaji, kama tarakilishi yangu eneokazi na bado kuwa wamehamia kwa Debian, Itakuwa kutumia Ubuntu eneokazi. Ingawa kama PC kwamba una tu kutumika kama seva ya mimi kupendekeza usambazaji Seva bila kiolesura cha michoro, hasa kama PC yako kufanya hivyo ni P4 na.
