Recommended Hardware for SSAS 2012

Hi All,

Currently we are going to migrate SSAS 2008 R2 to SSAS 2012 for one of our clients. Just looking, what could be the best hardware for SSAS 2012 for this migration. 

Here are our requirements:

There are a lot of cubes. Max size of the one cube is 78GB. There are several cubes sizing from 15-25GBs.

There are lot of Dimension in these cubs.

There is lot of data.

Looking for recommendations about followings:

1. What should be the size of the RAM?

2. What should be the size of the HD (Is normal HD is fine or we should invest on SSD)?

3. What should be the speed of the CPU? Which is better INTEL vs AMD?

4. Does OS play any role as well?

5. Any other recommendations if I have missed something. 

Please bless me with your expert advise and mention some useful recourse about this topic. 

Please don't hesitate to add if I have missed something.

Thanks,

TA
