mini ITX build

[FuNKieJuNK]

Hi all,

I'm putting together a SFF PC, and was hoping to just get a sanity check to make sure I'm not overlooking something before I buy it all. I'll primarily be using it as a HTPC, along with some various video encoding. So ideally, it'd just be some small, quiet, and out of the way for the most part.

Case: SG05 450W
Board: Gigabyte H67
CPU: i7 2600k
Cooler: Thermalright AXP140
Case Fan: CM 120mm
RAM: 4G Kingston
SDD: 120G Intel 510
Optical: LG Slim Combo


A couple questions:
- Anything I'm missing? Anything I should change?
- How quiet will it be? Suitable for HTPC?
- Any issues fitting all the components/heatsink?

Thanks in advance for feedback
