 Thanks Aria by Muttley

I was in need of an upgrade, so I took the plunge and purchased one of these, it looks great and performs even better, only thing I had to do was set the time (I will be playing with the o/c when I have a little more time). there are no IDE slots but unless you have got an old DVD RW then it's not a problem, fits straight in a midi case (coolermaster, a little old now) without any problems, all in all I am really pleased with this board (it was hard to give up on ASUS but glad I did)
