alexalex9998, I'll assume you meant WPA and not WEP as WEP requires nothing more than the simple aircrack-ng suite and a cheap laptop due to the initialization vector attack we have matured over the years. Not to mention it's so rare to come across an SSID using that these days.
Here is what you can build: A motherboard such as GIGABYTE GA-990FXA-UD5 AMD 9 Series has 6 PCIe slots or Supermicro-X9DRX-F-B-Dual-LGA2011-Intel which has 11 PCIe slots. You can get a couple of 1200 or 1500 watt power supplies and daisy chain them safely with a little module from add2psu.com. You can use a long milk crate or a custom built aluminum/wood frame for mounting your GPUs. You'll want to use Ubuntu Server 11.04 LTS if you can. 1x-16x PCIe riser cables will make the spacing of your GPUs much easier for air flow. The best cards to use are either R9 290X or HD 7990. Yes, epixoip and his Sagitta systems are solid and if you are a company, a warranty and support are something that may be worth it's weight in gold rather than building your own rig and risk making a mistake. (Invictus is at your price range, but building your own rig would be cheaper and faster)
No matter how attractive Wikipedia says the GFLOPS are for the R9 295x2, trust us, they get too hot too easily, will throttle your workload, are a hassle to tweak/deal with and ultimately they will negatively impact your goals. Do not use them. Please spread this gospel.
