I did not find anything in PowerEdge line of products that met my requirements. Closest thing I found from Dell is the Precision R7610 (rackmount workstation).
I'm looking for a Dell PowerEdge server that can hold two dual slot PCIe x16 cards (full-length) and two PCIe x1 half-length / half-height slots (single slot). Preferrably a 2U machine as a 4U machine would take too much power.    Does anyone know what model would work best? Anything from R610/710/810 series to R630/730/830 series would be great.   Thanks!
