Alright, so I have an "upgrade" plan for my Power Macintosh G5 over the course of the next half-year. They consist of RAID/HDDs, Graphics/Monitors, RAM, and XGrid/Network. I'm going to lay down the plan here in a semi-ordered manner 1. RAID/HHDs; Currently intending to use four WD1002FBYS drives and the ARC 1680-ix8. My main question is the SAS->SATA connections; should I distribute the HDDs connections over the two internal connectors, or would one expander work fine for my setup? (BTW, RAID5) For that matter, can anybody recommend an expander from experience? Also, should I be worrying about power draw from the four HDDs I'm fitting in since the G5 wasn't made for running five total drives? Speaking of which, to fit in five drives? Four go into the optical bay. I have plans on making the internal enclosure fit where the optical drive sits - just need the school plasma cutter. My BIG question on hard drives is this - How can I make the already included internal G5 bracket more secure? Recently was dragging and dropping some large files and the thing sounded like a chainsaw! Pushed it in a little more and the sound died down, but in the meantime its a little disconcerting. 2. Graphics/Monitors Well, I'm going to plan on running a three-display setup as my last priority - and instead of buying another graphics card, I was planning on using the dual-link DVI port on my 7800GT to power a TripleHead2Go for running two 1900x1200 monitors. The single-link DVI port would then power the third monitor. I assume there is nothing wrong with doing this on a 7800GT? Also, I know the best card for a PCIe G5 is the Quadro, but should I consider trading the 7800GT for an X1900 XT? I know there are different gaming benchmarks on Barefeats, but I'm going to be using FCS2 with the system; gaming is not important AT ALL! I just want to know which will be better for applications like Final Cut and Adobe CS4 over the three monitor setup. And as for monitors go, I was planning on getting two more DS-263Ns with a certain polariser used - probably hoping to spend for them $1100-$1200 shipped. I could get some PX2611s, but at the same time I'm also trying to match my current monitor which has said special polariser (A-TW, as for as I know). I know TheStrudel has one of these 3. RAM Simple. I have 4GB now and want to expand myself to a good 16GB; preferably ECC, if the G5 supports it and if the "price is right", for lack of a better term . Any suggestions? I've used some non-G5 RAM in it before, but that turned the machine buggy as it was then running at two different RAM speeds. 4. XGrid/Networking Alright - so there's the potential I may be getting another computer specifically to send render jobs to - first, would I NEED XGrid, or would simply opening the project in the other computer do? It would have to access my RAID array that I would be putting in my G5 in the first place; furthermore, networking is also a problem. Should I consider port teaming my G5 and the other computer? In that case, would I need a router that supported 9k jumbo frames or could I just connect NICs? Also, for XGrid, would I need OSX server on one/both machines? [/curiosity] Thanks for taking your time to answer my questions.
