I did it! I actually built my own PC!
Just got the H50 on, connected everything and it posted 1st time! (hope i'm not tempting fate).
Thanks to everyone on the forums here for answering my dumb questions! You help is really, really appreciated.
Just ordered Windows 7 student so will get that in when it shows up next week.
One thing - the bios hardware monitor says CPU temp is 39-40 degrees. Is this OK? Its an i5 760.
So frigging pleased right now!
