I recommend this, but I would get a 120GB ssd and a 1TB regular hdd instead of a hybrid drive.

I would also get this Xeon instead of the one listed. It's newer and $4 cheaper. partpicker hasn't added it yet.

300-350w is plenty for this system. If you are not familiar with those Xeons, they are basically i7 4770s. The 1246v3 in particular is almost the exact same chip except the Xeon runs at 100mhz faster base speed and will actually run cooler. It's igpu is a little better too. It's really just a better i7 for about $30 cheaper.
