Hey mate, thanks. To answer some of your questions;
1. The case is fantastic. I looked hard for something with great airflow, but no stupid flashy lights, or windows, or crazy designs. This case has a mesh front and top giving it very open and cool airflow + 3 fans as standard. The LED's at the front can be turned off too which is great. Overall it looks and works great.
2. 4GB of RAM. If you fill all 4 slots its harder to overclock. I think this is true on every platform (though 6 slots for LGA1366). Also I have never found my system maxing out on RAM usage. Really no need for more.
3. Massive cooling tower

Noctua NH-U12P. Comes with 2x120mm fans. Don't worry about motherboard stress. The mounting kits are well designed and the motherboard can easily handle it. The stock heatsink and fan is too small for any overclocking.
4. CL are a great store. I chose all the bits myself, but they'll give you a discount off any combo of CPU, mobo, and RAM.
Been playing around and I'm still blown away by how amazing FSX runs now. It absolutely screams along. It's gone far above and beyond what I had ever expected. If you're building a high end system on a budget I highly recommend the i5-750. Great little chip. If you have the dosh though, I would recommend the i7-930. Either way, you will have to overclock to get these great results. Not sure where you got $3k from, unless you really are going to buy the best of the best. I think with $2k you could build an extremely sweet machine (minus monitor, keyboard, mouse). Luckily I already had the graphics card, a decent PSU, and 3 HDD's. I think it would be a waste of $1k on upgrading an obsolete/old platform. Let me know what components your thinking of and I'll see if I can help. I spent a good 2 weeks reading and researching before I bought my bits so I'll probably be able to give some advice.
