Ok thank you
I'll test the e2220 and publish the results here to say if it's powerful enough, if not ==> Q6600
for the 24" lcd I guess I can play on a lower resolution then, because the minimal one for the 19" is 800x600

for the Hard drives I'm thinking :
1Wow.exe on the old IDE 20GB maxtor 5400rpm
2 wow.exe on the old IDE 120G seagate 7200rpm
2wow.exe on the new S-ATA 500GB seagate

And with my main screen coming from the 20GB one maybe...
