By reading your thread, i remembered, that i have an ASUS P4T, too
The first P4 was so slow

When i have time, i think, i will build an simular system as yours. The Indigo Orb is so nice, unfortunately i can't find CPU Cooler for the 423 sockel, which looks great as the Indigo Orb. Have you any idea, mabey a full copper Cooler?
I would be that person who has two new old stock TT Indigo Orb's. I was already trying to sell them as I have no socket 423 system myself.
If you want to buy one from me send me a PM. I'm asking 10€ a piece. Shipping from NL 
OT: Also this is my first post on this forum haha
