I ordered the stuff now, and I only changed few things:

- got the Antec 1200 case
- got the Patriot memory, 4GB
- got the Arctic cooler you mentioned Harrison
- got the Cougar S700 PSU, not the 700CM, which is a bit more expensive but has an 80+ silver certificate (the other has "only" bronze )
- had to change the 5770 Asus card, as Asus cards and many others were out of stock, so I got the Sapphire model (still 5770)

- kept everything else, the CPU, took 3x 2GB HDDs, and the Asus mainboard
