Please note that because the forum now only allows a post length of 20,000 characters, I have had to cut this OP and add the updates from it to the end of the thread. They are linked below, at the end of this first post. All future updates will be posted in this way. Current Farm Specs (GPU's only); Geforce 8800GTS 320MB - 345.6 Gigaflops Geforce 8800GTS 320MB - 345.6 Gigaflops Geforce 8800GS 384MB - 396.0 Gigaflops Geforce 8800GS 384MB - 396.0 Gigaflops Geforce 9800GT 512MB - 576 Gigaflops *NEW* Geforce GTS 250 - 705 Gigaflops *NEW* Geforce 8800GS 384MB - 396.0 Gigaflops *NEW* Geforce 8800GS 384MB - 396.0 Gigaflops Total - 3556.2 GigaFLOPS / 3.5562 TeraFLOPS --------------------------------------------------------------- I thought since we (Read: I) have been discussing this left right and center in some way in several threads both here and on the old CPC forum, I would consolidate what I have worked out so far into one single thread, and then any questions that I or any of you have to ask can go here as well. I plan on making this a project log once the build is underway, but for now it is in the planning stages. Hopefully by the time I come to build it, I will have planned everything well enough to make sure that I don't hit any problems. Outline of the project For those of you who don't know what I'm talking about; I have been planning to build a Folding @ Home farm for the past month or so. The loose definition of a farm is "The concept of taking two or more computers and organizing them to work together". At the moment I plan on including 4 rigs in the farm dedicated to folding, with another acting as a large capacity file server. The GPU2 client will be what the farm will run mainly, although I also will run notfreds VMware SMP client on whichever CPU's will support it to obtain maximum points. The cases I had originally planned on using 19" rack cases the same as what Nitteo's farm is built in, they are these from Xcase although in his footage and stills you will notice that he has removed the locking front panel presumably for better airflow. Nitteo has a very impressive farm and I want to mimick his in some ways, but in others I want to employ my own design features and put my mark on it. I also like the setup that Atlas Folder has, and although it's a very neat and well put together farm, it is built in open frame type cases, which would mean lots of dust and dirt and not much directional airflow over hot components in my case. I can only assume that Atlas Folder runs his farm in an Air Conditioned, clean air server room and for this reason the open frame design of his farm makes sense. Saspro showed me these, which are available with the option of a 19 PCI slot back plate. This feature, as he rightfully pointed out, brings up the possibility of having 4x dual slot graphics cards in a rack case, which would be ideal because most dual slot cards have coolers that exhaust hot air out of the case, keeping the internal temps lower. I think that these cases are ideal for my folding rigs. They have 2x 120mm fans to draw cool air in at the front, which have the additional benefit over the intakes on the XCase XC RM 400/10 of having dust filters. The Compucase also has an optional 14 slot backplate, which will allow the case to hold 4x dual slot PCI-E graphics cards, or possibly more with the right motherboard and some tweaking. I had placed an order for one XCase XC RM 410 yesterday (08/05/09), however after seeing the better equipped Compucase I changed my order to one of those instead. This case is going to house 2x 8800GS's and an A64 X2 6400 Black Edition in an MSI KA92 Platinum for now. Hardware list - currently owned – Updated 09 October 2009 This is a quick list of what I currently have to put into the farm. I will be adding to this once the cabinet is started, although I still don't know what exactly I want to end up with in there when all is said and done. Needless to say I will be looking for bargains on nvidia graphics cards between now and August! What's below is what I currenly have running for the Chimps Challenge (as of 07/05/09) and will not necessarily be what makes it into the farm in the end (i.e. my lowly single core media PC - that's just a host for the 9800 until my new KA92 comes!).

More to come later tonight on what cabinet to use, location of the 6' tall farm and cooling.
