So Im a freelance Editor/Motion Graphics guy with no real understanding of RAID Controller Cards, or how they work.
As of right now I have three 1TB drives inside my Mac Pro, RAIDed together (stripe 0) using the OS. No Raid card.
The drives are all 7200rpm from varying manufacturers. (not sure if this matters.)
My questions is; is it beneficial for me to get a RAID card to control these drives vs. leaving it to the OS to handle? Any suggestions for me?
Thanks.

3 drives in RAID0 ? Yikes, anyone of them goes and your machine is out of action. RAID0 offers no fault tolerance as no drives in the array share parity info or are mirrored.
You would most certainly see a benefit in a hardware RAID solution, especially if you are going to switch to a RAID level with some redundancy, like RAID5 or RAID10. Also a true hardware RAID takes the processing load off your processors and memory.
If on a budget you could go with RAID-Z, it involves switching to the ZFS file system. RAID-Z1 apparently offers similar performance to RAID5. Read this thread (http://forums.macrumors.com/showthread.php?t=1135718) for further insight.
I would get an SSD for the OS and use the 3x 7200rpm Disks in RAID5.
RAID5 is great for storing uncompressed video data and in your case would offer protection against a single drive failure.
or Just RAID5 with 3x HDD's and partition the RAID volume.
The most recommend cards right now are the Areca 6g 1880 series or the new ATTO 6G series. For your needs something like the ARC-1880-i SAS 6G RAID Controller would suffice if you don't plan to connect external RAID/Storage solution.
I would go with a 6G controller so as to take advantage of new fast 6G SSD's etc.
nanofrog is the RAID-whizz around here and I am sure he would be able to suggest something for you.

Considering all the times i've almost been mugged, and that one freaking time my ipod touch was taken in a matter of seconds.. i wouldn't mind getting one of these. =P
The iGun is probably more effective, not too good to hide at the beach, though. ;)

Pages is perfectly fine for word processing, which I know from experience as I been using it for that purpose every day for nearly two years. Most of the people who say otherwise either haven't learned to use it or would have preferred that Apple produce a Word clone. Some of are very happy that they did not go that route.
I must Second that.
Office isn't even installed on my PowerBook anymore, and I've been using Pages and Keynote quite successfully on campus (where lots of classes and professors want lots of word and powerpoints all the time) for two semesters now and am glad I made the switch. I'm excited to hear about Lasso.

My MPB has a 200GB hardrive. I'm running 32 bit Vista. I tend to play Windows games so I allocated 80GB to Windows but then purchased two small (3x5x.5") travel hard drives- a 200GB drive for Windows and a 500GB drive for Mac stuff. This arrangement has worked well for me.

Do you pay your electricity bill?
Also that is one sure way to fry your Mac. Power surge can happen at any time.. Do you really trust those $100 surge boards for 24/7 use or do you have UPS.
Also think of how much dust gets in there...
Not smart to leave your computer on 24/7.
Are you kidding? The OP is just making a point about how good a mac is vs. a pc. If I even think about leaving my pc up for two days it will shut down just because I had that idea. The OP also stated that he had to leave it up to run a project for that amount of time.

Just do a 7 pass secure erase (35 if you are super paranoid and have some time to waste) using disk util from the boot up thumb drive.
This will have absolutely no effect on SSDs (http://cseweb.ucsd.edu/users/swanson/papers/Fast2011SecErase.pdf) beyond simply wearing them out. A single pass is more than adequate.

I say go for it. All signs are pointing towards the big improvements this year being in software updates. Will the new iPhone have faster specs and a better camera? Yeah. Will it be dramatically different than the i4? I don't really think so. I think the i5 will have a few hardware upgrades and a LOT of software upgrades that the i4 will also enjoy.
So you've got that on the one hand and the fact that it's not coming 'till the fall in the other hand. Put them together and I don't think 'buy now' is bad advice.

I have been working on a magazine for this whole week (Quark Xpress v6) and finally got it signed off yesterday. Shut down the computer and had a well earned drink.
When I turned on the computer this morning the document has reverted back to last Tuesday! (meaning a lot of lost work).
Would this have anything to do with changing permissions? (I did play around with file info on some other files.)
I have 15 other jobs going and they all seem to be fine.
I have dual 80gb hard drives - and yes, after every big lot of changes I backed up the job - but the backup drive says the same!! Anyone with any help would be greatly appreciated.

This is a total wild shot, but you're sharing your iTunes library over the network, right? It appears to be trying to make domain name accommodations for your iTunes library. I'm not sure if that's standard operating procedure or not, but it seems strange to me. Try turning that off temporarily and seeing if you get the same keyboard lock?
If you don't, then perhaps it has something to do with the way iTunes sharing is set up... if not, it was a wild goose chase. Sorry. :(
Oh, and at this point, if you haven't already, do just repair permissions for the heck of it. You never know.

They both sound way too expensive for the specs involved. You should be able to find a DP 2.0ghz Powermac G5 for around $200-250 these days. An iMac G4 should not sell for over $100 imo, unless its the rare 20" model.
If you are short on cash but still want some power, look towards the higher end Powermac G4's. A DP 1.25 or 1.4ghz powermac will outperform the SP Powermac G5, and can usually be had for about $150.
Like the title says. It really REALLY depends on where you live for mac prices. I was shocked that prices where cheaper in Alaska before I moved here to california.
There were ton of great deals on Criag's List up there for gear, but down here close to Cupertino? Holy hell, you would think mac users are offering up their first born for a 1st gen 17' iMac G4.
I had to turn to Mac of all trades for a better deal. ( I do not work for them or are in anyway affiliated with them. But in my price range a few months back this single 1.8, now with a dual OWC from eBay was the best monetary solution to upgrade from my DA dual 533.

I had this when i got an imac a few weeks back... it's your desk. seriously!
Have a look at my previous threads and you'll find the details of the post and how i fixed it.

Picked up a new 2011 iMac today and had the same thing, isolate the imac from the desk and it will go.
I had 2x 21,5" on the same desk, at the same spot and none of them made the noise. Just this one, the 3rd 21,5"
Edit: the first 2 imacs were the low 21,5". The 3rd is the high end 21,5". The hdd is different on my 3rd imac(1TB)
I read the thread you linked and i agree that it must be something related with the hdd

But, if you have mobility in mind you'd need the computer to be a notebook and work with a limited screen size or add an external display .... but then there's the plugging/unplugging all day, files need to be kept in sync...
What's your setup like, one computer or two, how do you use them?
One Macbook Air. No files to keep in sync since I don't have many computers and an external monitor isn't a problem. Of course if Apple knew how to make docks, it would be even easier, but it's not like plugging in 3 wires is sooooo much of a pain.
Having many computers is more of a pain than it's worth.
