It just comes with a preinstalled 360mm AIO liquid cooler. That thing probably makes up the bulk of the price of the case, because a similar cooler bought separately will cost about $140. However, the thing with coolers like that is that they're meant for extreme performance and heavy overclocking, whereas you... well:
You would be much better off (in terms of value for money) with a standard air cooler HSF for sub $50.
The Rosewill Arc PSU might be fine, but I can't confirm that cos there are
no reviews of the unit, or other units in the series. To me, a $2000 PC deserves a Gold efficiency unit with top quality capacitors and excellent performance. 7 year or longer warranty would als be on my shortlist. Arc has Bronze efficiency, and the fact that it has 3 year warranty and is built by ATNG (not so highly regarded but probably fine) suggests that it's a budget oriented unit and capacitor quality might be lacking.
I would recommend:
EVGA 650 G2 $80 AR - Gold, 7yr warranty, excellent quality and performance, very very quiet, fully modular cables
Phanteks Eclipse $70 AP - white, windowed, similar internal design to Genome
2 x
Bitfenix Spectre 120mm $10 - extra fans for the case, it comes with 1 front and 1 rear fan, put additional fans at the front for a total of 3 intake fans
Arctic i32 120mm HSF $25 - plenty for mild OC, very quiet
= $195
-> save $55, get much better PSU and more appropriately sized cooler
Or if you want a liquid cooler,
Arctic Liquid Freezer 120 $65 and
Liquid Freezer 240 $100 are pretty good, they use the same quiet max 1300RPM fan. With a liquid cooler you can drop one of the extra case fans, perhaps both. Install the 120mm cooler in the rear slot or 240mm in the front of the case.
