Corerection: Gateway G6-400.
My computer that I am trying to use Linux on is a Gateway G6-400 with a 10 GB hard drive and the original floppy and DVD drive. I want to use additional parts that are useable from an old Gateway Essential which consists of: the hard drive, some RAM, and another 10 GB hard drive. I want to use a OS that looks like a Mac (I am thinking about either Ubuntu or Xubutu). It doesn't have a 4 pin MB connector. Does this mean I can't change the power supply on the machine, or is the computer able to use the PSU without the 4 pin connector? How much wattage would I need?!!! And what Graphics card should I upgrade to for this computer? I want to do basic tasks and play these three games: Wizard101, FreeRealms, and Fusion Fall. All of the internet I want to connect over a network wirelessly. PLEASE HELP!!!!!
