Hello again, I swear I've seen you somewhere else...
😉 glad you got the thread up and running

so to the build. I'd stick with the first one personally. 16GB RAM and an i7 is overkill for Skyrim, no need to spend that much

switch to an XFX power supply as well if you want - there's actually nothing BAD about Corsair CX power supplies, but the XFX will likely be better. the only thing you should definitely do is switch to either a semi-modular or fully modular PSU, this means you can pick and choose the cables you need and it'll be a godsend when you get around to building the system. Corsair do a 'CXM' series, but you can narrow down to modular via PC Part Picker to look for other versions. Maybe take a look at the Corsair RM series - silence optimised, will go great with the Define R4 (great choice BTW, I recently bought one myself), and a lot more efficient, plus it's fully modular

I'd personally swap the RAM to this:

😛 up to you though

also, slightly better motherboad for overclocking:
http://uk.pcpartpicker.com/part/msi-motherboard-z97gaming3 (I think, given the addition of extra heat syncs, hard to tell in reality though), and also slightly cheaper than most of the ASROCK listings I could see - correct me if I'm wrong and the asrock was cheaper. And a better GPU - a bit cheaper I believe, as well:

😛 my only other suggestion would be perhaps get a SSD - will help with faster boot ups and loading all those mods
