Okay... I want to build my own PC for music as cheaply as possible. I already have a 120gb hard drive and a delta 44 sound card that I can transfer from my mac. How much am I looking at and what do I need. (I want the fan to be quiet but not too bothered about it being the quietest thing ever). Obviously it needs to be high powered enough to run Cubase/kontakt and a load of plugins but I'm not too concerning about it being the fastest spec available or some shit like that. I just need enough to get by.
