Current price of this model is around 520quid incl. pcexpress FW card. The cheaper ones are with 667Mhz FSB and this one has 800Mhz FSB, though.
I was also looking on Macs, but I didnot find anything in this price range which would be close to the specs of this HP. I am bit worry about second hand stuff, esp when its bought from abroad...
Filterz: cheers mate. I forgot on soundcard, haha. Now I have internal E-MU1212M on my desktop, so I will have to check for some not too expensive solution and buy it..
