Here's another thing. I'm having second thoughts on that Antic Sonata Case. I don't think it will adequately cool a crossfire setup. One last thing, will you be doing professional work like CAD, 3DS Max, MAYA, Softimage, Photoshop, Premiere, AVID Ect. at all. If that were the case I would get an Nvidia SLI setup because of CUDA (which allows the processor and graphics card to work better as a team, instead of separate units), and throw those Crossfired 5850s to the curb. Don't be fooled however, this is not very important outside the professional world.
Anyway, I will find you a different case that will effectively cool the setup. Think over what you may be doing in the next few years. If you like games, or movies enough, you may want to try your hand at game design or sfx.

Here. This case is HUGE, and well cooled. You should be able to fit in and power another G-card if you so choose. This case will stay super cooled with that huge fan on top and the two in the back.

hey there once again thanks again for all the research you've done for me i am very grateful I don't think I'll be doing any of the professional work you listed I will basically be using this for gaming and maybe if i can i'll insert a blu-ray player in the next couple of years. The set-up you have selected looks great but I am a little concerned as to how it is to put it all together because I'm definitely no computer expert. Is it just a matter of slotting everything into the case? and i take it i should get the second case you've selected because of the crossfire cards? cheers

hey again, my friend just advised me that if i want to play top of the line games the CPU should be at least 3Ghz is there any truth to this or will the one you picked out be sufficient?

2.66 is more than sufficient for any game currently on the market and if you wanted I can do some research into overclocking it. Mine is, but my friend did it for me.
3Ghz for games seems a tad overkill to me. After all I've seen a single core pentium 4 at 2.2 play crysis on very high. Alot that goes into your system already is overkill. The Dual Graphics, The Solid State Drive.

To answer your previous, I would be happy to list instructions when you order. It isn't brain surgery so don't worry too much. It is mostly like "Put part A facing upward into Slot A.". Not complicated at all. Also "ATX" is the standard telling you parts will fit together. No worries on part configuration.

Instructions would be very helpful once i get the parts, however I'm having a bit of trouble getting the money I need would it be OK if i P.M'd you in a month or so and hopefully i'll have started.

Sure, Go for it. Any time you are ready.
