Q: I'm almost certain they don't have this, but I want to come as close to it as possible. My dream is to have a 4 or 2 processor dual core system with the 2 graphic cards I think its called SLI. I saw something about 2 dual core processors but it wasn't a motherboard. It was something called a rackmount. I have never seen these before and don't know how they work. My question is what is a rackmount, how do they work and could I have dual processor dual core dual video card system?

A: Rackmount cases are computer enclosures that slot into a standard electrical equipment rack, allowing you to have several full computers and related equipment in a single secured and easy to organize enclosure. There are several standard rackmount case sizes, generally categorized by the amount of 'units' (spaces in the rack) that the case takes up. Most common are the 1U (one unit) cases which are only 4.4cm tall. Rackmount cases are almost exclusively used for servers, since business applications benefit the most from the density and security offered by rack mounted systems. Also most of the videocards, heatsinks and peripherals favoured by the home desktop computer market will not fit into a 1u or 2u rackmount case.

A rackmount case is not going to do what you want it to, so you'd be better off finding a non-rackmount case motherboard that supports the features you are looking for.

Currently the only motherboards available that support dual dual-core processors are for AMD's Opteron 64-bit server processors. Now there's nothing about the Opteron that says it won't make a perfectly good gaming chip, since it's essentially identical to the dual-core Athlon 64 X2, but the processor is more expensive and harder to come by, and the same goes for the motherboards. Tyan does offer a dual/dual Opteron motherboard which it claims is SLI compatible though. You'd require a special case as well as a power supply to support it.
