Any PC of those sorts of specs will do the job. Make sure you get a firewire port in it of course and plenty of HDD space, especially for HDV editing.

Also, don't forget to budget for thre s/w. premiere Pro 1.51 and Cineform Aspect HD together could cost more than the PC you're putting them on.

A quick glance shows that Aspect HD with the Adobe bundle (Premiere Pro, Audition, Encore and AE) will run around £700 after VAT.
