Opticaly I would go for the first, the Thermaltake - it looks rock solid, is prepared for BTX.... looks awesome. But if you read the text for the third case [bis zu 18 Laufwerke kann dieses Monstrum fassen!!! Das ideale GehÃ¤use fÃ¼r User mit einem Hang zum Ãœbertreiben oder als perfekte Herberge fÃ¼r ein Server-System!] Up to 18 drives can be put in this monster. The perfect case for users who want to show off or who are going to setup a server-system... It might be a hard decision... No, take the first one. That is an awesome case!

I did try to put my HTT multi from 4 to 3 in order NOT to overclock it and started Memtest+ without any problem ... I raised FSB to 270 and lowered CPU to x8 instead of x9 and PC startet ... raised Fsb to 288 which results in 2304 MHz CPU which was working before, too
