I want some data redunancy so I'm going to take parts out of my old media center PC that's sitting in the basement and turn it into a RAID 5 server, using software raid in linux. I'm going to take these old parts: AMD Athlon 64 X2 4400+ Cannibalized 250W PSU DDR2 800 Ram and plug them into a new MOBO: Jetway MOBO with integrated GPU (Radeon 3100) The new motherboard has DDR2 1066 slots. Will my old DDR2 800 ram work with it? Also here's the case I want to use: Antec 300 or maybe a 200. Everyone says it's ugly, but I like the look. Now some questions: Will software raid 5 be good enough for a media server? Will the integrated Radeon 3100 be fast enough to play HD video?
