Please help me build a HTPC! Mini-ITX or MATX?

Hello.

I got a fileserver with some music and movies on and I would like a PC in my livingroom that can access it and play it on the TV/stereo.

I got two diffrent setups in mind, maybe you can help me deside?

The first one is based on a Lian-Li PC-C35B case and a Intel E4300 CPU. Im not sure what MB i need and also how the fan on a E4300 will work in this case since the hight is so low (only 9cm). Do you have any suggestions?



The 2nd one I am considering is a Mini-ITX from Silverstone. The case, Silverstone SST-LC09B looks very nice with a 60W PSU. Im thinking of a VIA EPIA MII12000G motherboard/cpu, but im open to suggestions if you know something better.


Both use a 3,5" HD so I would also appreciate it if you know any good, SILENT HDDs. I only need enough GB to store a OS and some random files, so anything from 40GB and up is fine.

I hope those who know what they are talking about can lend a helping hand  

I havent desided what OS to run yet, but in any case there will be a bluetooth key/mouse connected to operate it. (no remote)
