Hi, O.K., I'm ready to make my mac pro purchase. (First Mac, because I'm a PC guy, and being a Beatles fan, I won't say Apple). I hope that people here will give me their advice because I have found these forums to be the best computer forums on the net (and I'm on a few). I want to do primarily audio recording (buying an RME Fireface 400 audio interface, and probably starting with Logic Pro) and video editing (Final Cut Pro), so I was waiting for the 800 Xeons to come out, hoping that the 400's would go down in price. Apparently this hasn't happened (yet). So, here's what I would like, and what I'm asking for advice about - Mac Pro - should I go 400 or 800? If 400 I think I'll go 3.0 - 3 internal hard drives (1 Mac internal and 2 third party - which should I go for given that I want quiet, large storage drives of at least 300 - 500 GB each? Does firewire 800 have to be a consideration or should I go firewire 400?) - I have no idea about graphics card - What third party monitor(s) should I go for? Think I'll make do with a single monitor at first, then go dual - 3 GB RAM - minimum Mac configuration and the rest third party Additional questions - How difficult/easy is it to physically add a third party hard drive and memory to the Mac Pro? Would I be able to do it myself without any horrendous hardware/software problems? - I understand that Mac Certified RAM is the way to go - does anyone have any recommendations about where to get this (I'm in Toronto)? I have read that there are some modifications that one might have to make in order to minimize heat build up. Is this right? - Is it better for me to go with a minimum system configuration and then upgrade later? What are the potential hardware problems with upgrading later? I understand that voiding the warrantee is one of these. I'd very much appreciate any advice that people could give me, Thanks, Geert.
