webserver on the move

As yearly fees for servers in Germany increase I have decided to run my own home server. My needs are not that high to reason a dedicated machine, and I win a workstation. And, after all, I already had to setup a broadband connection at home.
You are charged 0.20€ (about 0.25 USD) per kWh here [German Market History, mirror], therefore energy efficiency is very important. And, AMD64 servers are efficient.
Therefore my old Celeron D 2.2 GHz w/ 512 MB RAM rented server will be replaced first weekend in December by my new 2.2 AMD64 Quadcore w/ 8 GB RAM. The big chassis already contains a suitable motherboard with four Western Digital WD6400AAKS (review at PCGH) hard drives, so I need RAID…
(BTW, the whole system is nearly unhearable. A big Scythe Mine and two SFF21 produce 0.5 sone at 60 Watts (idle). System is 26°C, HDDs 34°C and CPU 28°C.)
