I picked up one of the standard size Top Decks late last week, and been loving it! Sometime down the road, I'd like to get a second one.
At any given time, I have 3-4 mobos set up on their boxes, but I can only run two at a time on my workbench. I usually only run one, leaving much of the bench clear for installing into cases, repairs, yadda. I can work with two running, but it is a little tight and risky for marks and scratches, bumping things, so most of the time I'll shut one down and put it aside if I have a full case that needs to go on the bench.
Aside from the obvious ease in swapping components or even motherboards, I was hoping this would allow me to run two out of case systems at once, and still have enough room on the bench to work with a case or complete system. While is does save a bit of space, it's nowhere near enough for what I want, and I think my imagination was completely out of whack to think I could pull it off!
It's not really why I bought it, I was just hoping.

Sometime this summer I'll be extending my bench anyway, doubling it's length. So I'll have a dedicated area for open air testing, and will easily fit two of these as well as one more on a mobo box.
Where it comes in extremely handy, is when I'll need to break out of the testing and clear the bench of all the junk to make space for maybe a rush job in a case. With this thing, all I have to do is shut down, disconnect the power cable, keyboard and mouse, and pick the thing up and move it to a smaller side table. Before, I'd have to pack up the PSU, opticals, hard drives, all the litter that sits on the lower level of the Tech Station. Same deal with going back into it, simply plunk it down, plug it in and fire it up.
Like the review says, swapping a mobo in this thing is stupid fast! It's pretty fast to swap a mobo on a mobo box, but it takes longer than the Tech Station because of all the litter and cables everywhere -- a certain amount of care has to be used and that takes a little more time.
The only thing I noticed, and it's apparent in the review pics as well (even though his is a larger version), all the wires and cables have a tendancy to spring out from the sides, making it's footprint larger than you'd expect. I managed to minimize it, but not eliminate it. So you do need a few inches clearance around the thing for room to work and cable-barf.
I would have liked the PCI support to be a little stronger, it flexes too easily, maybe it should even be metal -- very easy to replace I guess. I also have to watch myself when picking it up, there is a strong urge to grab it by the pci support bar and it is nowhere near strong enough to hold the weight. So I lift it by the underside of the top deck, is fine, I just have to remember.
It would be nice if there were a few extra screws with it. Not that you need screws at all when using it, just that you get the exact amount needed, and if you loose one...
I plan to drill a couple more holes in the top deck, so I can mount an Antec SpotCool fan for ram cooling, NB cooling or vid card cooling. One on the opposite end of where it's fan is mounted, and one on the opposite side from the pci support. It should then be able to cover nearly anywhere on the mobo that may require more cooling.
The supplied 120mm fan is quite potent, not sure if the cfm is published anywhere, but I am guessing it is well over 60cfm. It's not too loud either, louder than some would like but the breeze it casts on me a good foot away from the other end of the deck, is impressive (and a relief on hot days lol). It would have been nicer if the fan was a 3 pin with a 4 pin adapter... as it is, you need to swap the fan out if you want to plug it into the mobo and control it's speed or get the RPMs.
All told, I couldn't be happier with a simple product. I considered building something like this myself, yeah like I have time for that. The cost may seem a little high for what you get, but I know it will pay for itself very quickly in convinience, pleasure, and safety.
I'll try to find time to take some pics of it tomorrow, post 'em tomorrow night.
