the power is too low and

- I dont think you can even fit two doublesized cards inside.. and the PSU seems like it's implemented in the box somehow - a bit of a fail,
or you can fit them but you have to choose a 8x and 4x speed option (what happened to the 16x one)
- I would ask them what is the point of buidling this external box if it was made for single sized low power cards .. why would I want three of those in a box - only thing I can think is that you want to connect like 6 monitors - but you can connect 4 with a 590gtx anyway, but 250W is not enough even for that ..
You can always connect an external PSU to that (which you turn on manually via a paperclip), but it will look ugly cause the PSU will be outside of the box probably
why do they keep on making compromises like that - the box should have 8 double slot sized PCIe ports (or at leas a option to expand), that would be as big as a regular pc case though, or at least make it modular, and the case can be a skeleton - save on the price (I really don't care about how it looks, a skeleton case would even be pretty cool of a solution)
and sell them without a PSU - again saves on their price - because anyone can insert their own PSU according to their setup (they can give you options, but a option without a case and PSU should be one) - to which market are they aiming with this - it is underpowered for any GPU rendering options (250 W is enough for a single 580 or 590, maybe)
I would be pretty happy just getting the electronic board without anything - that would also reduce the cost of shipping, and the case.. less bulk, faster delivery - I am sure there have chinese counterparts that are producing the electronic boards for them, and others, and maybe we should find out which one it is and purchase from there, I could even have fun assembling a box on my own, a 3d cnc milling project
But I like the fact thunderbolt is supposed to work in this manner - this is the best solution yet, just have to look for more manufacturers, and which PC boards support thuinderbot - the damn problem is that I have old mainboards on all computers - and upgrading everything is costly - and I am pretty happy with my 2 year old pc, with 2xSSD in raid0 (working on around 500mb/s transfer speeds. and 24 gb ram - after introducing octane into workflow - CPU speed stopped being a concern to me) windows experience index on win7 is hitting the top numbers on almost everything, why upgrade, I only want to upgrade the number of graphics cards, we are still missing that holy grail of PCIe expansion
