Honestly, the price will stay at $149.00. The "Introductory" part will dissapear soon.
Sorry to hear you think the price is too high. I can attest that custom metal work ain't cheap, but things might be able to be streamlined to bring costs down if we have larger quantities to produce at once.
What's the advantage of using this to just putting the computer on the floor of the rack?
Does it clamp it in place so it doesn't move?
I have an IsoBox and am expecting a new G5 that I plan to put inside of it. I have a computer shelf that came with the IsoBox and I'm not entirely sure how it works (you just put it on the foam on the bottom, I guess?) but I figure that I'll figure it out since a bunch of people are already successfully using it.
What advantage would this give me? Is it to elevate the mac to a higher position in the rack?
This isn't a clamp-in type shelf. The unit just sits in the shelf, relatively loose (although we are putting clamps on the next batch so it will be secured).
The main idea behind this is that since the G5 has to stand up if it's in a rack (because it is 21" tall and can't sit on it's side between rack rails), this allows you to rack other rack mountable units sideways next to your G5 in the same part of the rack the G5 is using.
The picture on our web page shows the G5 in this rack frame with an expansion chassis next to it on it's side. This keeps the 12 rack spaces a G5 needs to stand upright from being totally wasted in your rack.
From what I can see, you don't need rear rails to use this -- is that correct?
I don't think you totally waste the space next to the G5 without this thing since, if you were putting the computer on the floor, you could just put another piece of rack mounted gear on its side. However, actually racking it in, as your thing-a-ma-jig lets you do, is obviously more secure and neater.
For me, actually, the big selling point would be that it enables you to lift the G5 up off of the floor of the rack unit, which would enable greater airflow, both around the computer, and into/out of the (enclosed) rack unit via a portal on the bottom.
I'm more sold than I was at first -- it's a clever solution to the G5 rack dilemna. It would be nice if it were just a tad cheaper, though, but I can see its utility. Even if I didn't use the space next to the G5 for a side-mounted piece of rack gear, the shelf would enable me to put non-rackable things there, and lift them up from the floor of an IsoBox which would be better for air circulation.
