The Magma boxes are very modular. They have a PC type power supply, the pci back plane, a card that goes into the back plane, a card that goes in the PC, and a connect cable.
If you google for similar products, there is a cheaper 4 slot unit from another company.
These PCIE to PCI boxes use Pericom chips. I suspect even the single PCIE to PCI converter cards would work if Pericom equipped. If it needs software, don't get it. These boxes should be totally plug and play.
Mine came out of a small recording studio. These probably get traded on specialty forums.
Thank you i'll by a 7 PCI slots magma box, it's amazing
