it is NOT a server
its more like an external hard drive, except they're all removable from a seperate case. Its just a box with drives. The drives all are IDE, and will have a powerless IDE to USB2 adapter. Then the USB cables for each drive will go into 1 of 2 hubs mounted inside the case. These hubs, ideally, are powered by USB and do not need an external power source (though, if need be, I have enough room to do some bizarre power source things (perhaps mounting a small strip in there, mounting the PSU transversly, and instead of using a normal PC power cable, I would use a 3 prong extension cord, leading to the strip, which would connect the PSU with a normal cable, and the two hubs). Then the hub's root data source (USB A plug...think thats the square one) would get mounted on the back of the case, where I can connect a USB A to B cable from my PC to it. Thus, it would be similar to having a bunch of external HDs connected to a USB hub. If you wonder why do this and not get a bunch of external cases, well, I have the removable trays for free, as well as this case.
So, basically, no motherboard, its not a computer at all
These drives will actually be local drives, not network ones.
I got the "idea" from a review Toms Hardware did in Mass Storage, think it was Alternatives to Tape Backup, and it was the 7 bay High Rely product. It costs more than $2k with seven 80GB drives (560GB)...
