New HTPC Build - $600 Budget Thoughts

I am building almost the same system this weekend. I will just be using this for TV, Movies, email and surfing the web (no games). I am doing it in steps, trying to re-use old hardware, save money and not add anything I wont use.
I gutted an older Dell with a broken motherboard and realized my Core Duo CPU wouldnt work with a more modern motherboard. I went with Intel Celeron G1610 which is the best value for around $50 and runs at only 55W.

Went with the same motherboard you chose (Rock H77M LGA1155) for $65 and I can upgrade the Celeron later to an i3-i7 if I need more power. I added Pioneer Blu Ray 207DBK for $50 and the Silverstone ML03B case for $60, a Rosewill 350W PS for $30 and ARCTIC Freezer 11 cooler for $18 (very quiet and low profile). The PS sucks so don't get that one, the power wires won't reach the HDs so I had to add some adapters for about $20. I have an old video card from the Dell and I will add that too. So right now I am in for $263.

I am going to re-use my old 250gb HD but if Windows won't work because I changed the MB, I will add a 128gb SDD for $98 and Windows 8 for $100. I aslo plan to reuse the 3gb RAM from the Dell because Windows 8 can run 64bit on 3gb ram. If that doesnt work, I will add 1 stick of 4GB RAM and if I need to upgrade, I can add a second stick later.

If I find it difficult to store stuff on my 2TB network drive, I will then add a 3TB HD for $130.

Full system if I add everything.
