Custom PC-building company AVADirect has been in the business for awhile, and we've checked out some of their solutions in the past, but today they have announced what they call a "one-of-a-kind Supermicro rack-mountable system" that allows a quad-SLI NVIDIA graphics setup alongside additional expansion cards for the first time ever.
The company says that this solution allows users to have best of both worlds when it comes to graphics and expansion cards, since the tower can fit up to four graphics cards while still making room for additional cards for other purposes. AVADirect says that most other similar solutions don't offer the same flexibility.
The motherboard featured in the default configuration (Super X9DRG-QF) offers four PCI-Express 3.0 x16 slots, two PCI-Express 3.0 x8 slots, and one PCI-Express 2.0 x4 slots. So essentially, you could pop in four graphics cards and still have three slots left over for expansion cards like a RAID controller or a network card.
AVADirect says that this kind of flexibility "truly shines and stands out from other configurations" that are offered by competitors. The system also supports Intel Xeon E5 processors and up to 512GB of ECC-registered memory or 192GB of ECC un-buffered memory. On top of all this, there's eight 3.5-inch hot-swap bays, and a massive 1620-watt redundant power supply to run the show. Of course, it won't be cheap. AVADirect's recommended build costs over $2,600.
