New Build - Comments/Suggestions Welcome

It's a good start but Thermaltake makes horrible PSUs and ditch the mATX board - your expansion options will be really limited. I'd also say ditch the blu ray burner for a cheap DVD burner and invest the difference in upgrading your GPU to a GTX 560TI or Radeon 7850.

Thanks. Suggestions for the PSU and the mobo?

The blu ray I am mainly looking at as a means to be able to copy blu ray disks. With two young kids it would be nice to be able to have back-ups.

If you use blueray, keep it. For your use, I would only buy 4 gigs of ram. You also would be fine with an I3.

Since your going with a Ivy Bridge cpu then you want an H77 board so you can use that 1600hz RAM. H61/67 boards do not support 1600Hz RAM and are targeted for Sandy Bridge cpu's.

Either keep that discrete video card or step up to the 3570K so you have use of the Intel HD 4000 graphics. The 3450 comes with the Intel HD 2500 graphics which aren't nearly as good as the HD 4000 graphics.

The bad thing about copying BD-R discs is that a lot of those discs have copy protection already which is why most come with the digital copy and DVD disc anymore.
