Looking to build a mini ITX based media server, but come to one slight hitch. Expansion As far as hdds go. I am getting a separate caddy to contain the drives, thats no problem. There are only 2 sata ports on the mobo (looking at an atom dual core job) and a single pci slot. i will need at least 4 sata ports as i have a sata hdd and sata dvd rw drive to put in it to run the OS. Most pci RAID cards (from my experience) have been pretty bad performance wise (pci bus bandwidth limitation?) my budget is around £300 for the complete system and most mini itx mobos seem to be around the £200 mark without cpu or case. The atom board is £75 on ebay. Any suggestions on what to get? thanks in advance
