Requesting for installation guide to install ecc 6.0

Hi gurus,

I have recently installed windows server 2008 r2 in my dell system(4gb ram, I3 2.55 GHZ, 500 gb hard disck). now i want to install ecc 6.0 in my lap for webdyn pro, adobe forms and CRM practice.

To install ecc 6.0 in my lap what all files i need to download from srevice market place. i dont want ehp4. as i did read in other threads ehp4 will be slow on my system. i kindly request you to please guide me in downloading appropriate files.

and one last big dought in my mind. if i go for crm and ecc 6.0 whether my system can run both the things successfully. how much space is needed for this thing.

Please do reply..............
