Can't really help you further then. The code is OK. It's a project setting somewhere. Maybe start with a fresh project and try again.

Cardboard and wood are good options

Build A has a newer CPU, which is also unlocked (notice the K in the name), it has more memory, but doesn't have a SSD (which I am a very big supporter of).
 
The second build doesn't have a unlocked CPU, which is also 2 generations older, but you do have a MOBO that can oveclock, so you could get a better deal if you opt for a MOBO that doesn't handle overclocking. 8 GB ram I find to be just enough these days so if I were you I would go for 16 gigs instead.
 
Both power supplies are fine I guess. 
 
But really you have given us way to little data to asess which is better for you.
Do you plan to overclock?
what games will you be playing on the PC, if at all?
How much "futureproofing" do you want?
Other more special needs?

FTL looks like it could be fun 

Okay.
 
If you don't plan to overclock you should probably buy the i5-6600 processor, as it is a bit cheaper for basically the same processor. Because you don't want to overclock you can also opt for a lower price MOBO, i'm not sure which one to recommend though.
Like I said 8 gig might feel a bit on the tight side, I play Black Ops 3 and it eats my 8 gigs of ram, so I would recommend the 16 gigs of ram.
As for the hard drive, try finding a WD black as they are more geared towards heavy use (playing games). I would also recommend an SSD if you have the budget left, they're becomming cheap as dirt nowadays.
 
The graphics card is great IMO, but it is a bit of a anoying time to buy a GPU, the new line are just released, with the aftermarket cards not far behind probably. So wating might be a good idea, but that said you won't regret buying that card.
 
That's my recommendation.
