Hi. Old desktop to be used for fresh install of Linux based OS. Currently has Win Xp Home SP3 running on an Intel Pentium 4 3.0 GHz with 496 Mb ram and a 74.5 Gb NTFS hard drive. No wireless, only LAN, has dvd drive and usb ports. I am wanting to go all out fresh install jump in with both feet kinda setup. I have looked at Ubuntu but fear its too heavy for the old box. I have read a lot about diff distros and just get even more perplexed. Usage is basic internet and media, photographic processing. What else to consider for an install for a complete Linux virgin??
