Ma soprattutto... 4 schede in un case chiuso io non le ho mai viste  Troppo poco spazio, troppa poca dissipazione del calore. Una volta sul forum inglese ne ho visto 4 in un case ma erano moddate con il raffreddamento a liquido. Anzi di avere un dissipatore per 2 processori, su 290 ogni processore ha il proprio dissipatore,questo case e' adatto alla massima aerazione, sopra si puo' posizionare anche un ventilatore domestico "alla americana" |

Sto valutando cosa comprare. |

I 'm talking about second hand gpus. A used 5970 should cost no more than 200$.
and no garancy |

Possono stare 4xR9 290 su Gigabyte Z87X-OC in Cooler Master HAF XB con ventola da 20"?   Se il raffreddamento non bastera', c'e' un altra soluzione:  |

Советую прочитать обзор http://www.thg.ru/graphic/radeon_hd_7990_v_crossfire/даже одну 7990, меньше чем до 90 не охладить в корпусе CM HAF X. + мой собственный опыт, что в корпус с хорошим воздухопотоком не справляется с даже с одной видеокартой (температура улетает 102+ и начинается сброс МГЦ) Если их поставить на Gigabyte Z87X-OC $220.17 со свободными слотами между карт, и дополнительными вентиляторами?  |

Maby i will put 4xR9 290X on Gigabyte Z87X-OC in Cooler Master HAF XB. But R9 290X are expensive at this moment.
I'm not sure you can without using risers, can you???.. Why not? There is enough space, 2 free slots between cards. http://www.youtube.com/watch?v=bujxzjnDTcwIf temperature will be too bad, i will put over cards, on Cooler Master HAF XB, some fan as on picture  |

you dont need a real case...
I like it, and there is no other problems, than price. For 2 cards i like not solutions as on this picture:  |
|
|
|
very little real benefit
for two 7990 is perfect, as i see |
|

No, NOT a good case. You don't want the cards so close to each other, so you want to use risers.
Just use a plastic crate as a "Case" if you can't afford/build an open frame
I'm about two Gigabyte AMD HD7990 . Gigabyte Z87X-OC $220.17    There will be enough space between two cards, no risers needed, and in this case is possible to have additional 20" fan ower the cards and two other fans on back side.  |

Questo e' quello che succede e che andrebbe evitato : In qel caso erano 2 schede 7990, credo, se si mettono senza riser in una scheda madre con piu' slot, lasciando uno libero tra due 7990, potrebbe funzionare nel case Cooler Master HAF XB http://youtu.be/L5fyk1YEeIU |
