Hi.

I am doing some research on hardware for CFD, because I am thinking of buying a computer. Sadly I cannot invest all that much. So I am looking for hardware specs with just enough for professional calculations and post processing: good speed, comfartable 3d data manipulation, good accuracy, and so on ...

Any recommendations?

And is there any literature concerning speed and accuracy issues for estimations?

The station I currently use has a E8400 6GB Ram with a 7900gtx. Which was thrown together as budget did not allow for new parts.

That said, the minimum I would suggest at this time, would be an Intel Core i5 - i7 and as much ram you can fit in your budget. A decent discrete graphics card.

Additionally: I think most of your budget will go towards memory, and possibly the graphics card.

Here is a parts list to get you started.
LG DVD Burner - Bulk Black SATA Model GH24NS50 - OEM

Western Digital Caviar Black WD1002FAEX 1TB 7200 RPM SATA

Radeon HD 5850 (Cypress Pro) 1GB 256-bit GDDR5 PCI

G.SKILL Ripjaws Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)

ASUS Maximus III GENE LGA 1156 Intel P55 Micro ATX Intel Motherboard

Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156

And welcome to the fora.

Thank you for your reply and warm welcome. I was trying to put such a list together. I will definitely keep your recommendations in mind, while choosing the hardware. And for the sake of a better overview (because I have the habbit of getting stuck on detail), would it be safe to assume the following connections:

For speed and accuracy: processor: as fast as possible and best 64-bit.
For a bigger or more detailed mesh (more grid elements): memory (RAM)
For better and faster 3d data viewing and manipulation: graphic card.

Is there anything else I should keep in mind that would be important?

Try to get the Fastest Cpu you can get with in your budget. don't buy old technology, Go for Core I5 or Core I7 and for the memory as you mentioned the more memory the more mesh element you will get I believe 8GB is good, for the Graphics Card if you are going to use this machine only for CAD CAE Stuff I'll recommend to buy Professional Graphics card Nvidia Quadro FX or ATI Fire Pro. this will give you better performance than the normal gaming graphics card.
good Luck
