 Like the Fastra I , the Fastra II uses a <unk> Li PC @-@ <unk> <unk> case , which has 10 expansion slots . The motherboard in the Fastra II was at that time the only <unk> motherboard that had seven full @-@ sized PCI Express x16 slots . The memory <unk> were initially six 2 GB <unk> , but were later upgraded to 4 GB each , for a total of 24 GB . Instead of an eighth dual @-@ GPU video card , the single @-@ GPU GTX 275 is in the computer because , out of all the video cards in the Fastra II , the GTX 275 is the only one the Fastra II 's BIOS can fully <unk> . The total amount of GPUs is 13 . The video cards together bring 12 <unk> of computing power . Four of the six GTX 295 video cards have 2 <unk> , while the other two have only 1 <unk> .
