Right, certain members here (you know who you are

) have persuaded me that I should build rather than buy. I'm going to have a stab at it but I'll probably need advice from time to time.
I am thinking of using the
A8V-E Deluxe mobo with a
Athlon 64 FX-55 Socket 939 and a
GeForce 6800Ultra--but the 512mb version which should be on sale soon. I was thinking of the
coolermaster CM Stacker (STC-T01) for the case as it's huge and appears to have filters for the air intake.
Any comments on this lot? Could I improve on my choices?
.........also, what ram should I go for?
