As I move onto my next project, I was hoping that a fellow modder coud point me in the right direction on a couple of things. First and foremost: does anyone make, or know where I can purchase a custom Mac Pro rear i/o PCB? I want to avoid cutting my case but still want rear panel functionality. I know zammykoo on insanelymac used to make G5 rear panel i/o boards, but I need a Mac Pro one. Any help would be greatly appreciated. Second, I am wondering about my power requirements for the build. Below is my list of components ASUS P8z77-M Pro i5-2500k (plan on OC to 4.7-5.0) Sapphire HD6850 1 GB 4 GB Corsair Vengeance LP x2 (maybe up to 4 in the future) LG Blu ray writer Samsung 830 128 GB SSD potentially 1-3 WD green HDDs Noctua DH-14 cooler 4 Mac Pro 120 mm case fans (these may be swapped for Noctuas if I cannot get them running) Internal Apple BT 2-3 USB devices I was looking at getting a silverstone as they are 100% modular and are 140 x 150 so I should be able to easily fit them inside the Mac Pro PSU cage. The SFX 450W is only like 120x110 but I am guessing that might be a little light for my needs even if it is 80 plus gold. Do I need 600? 650? or will the 500-500 be enough. Thanks.
