The Sense 3 fan controller is a PWM fan controller with multiple channels, where as the built in fan controller is a single channel, voltage fan controller, so they aren't really on the same level, although I do concede that the single channel voltage fan control will do what he needs.
Sapphire are considered one of the best AMD board partners, and the dual-X is the cheapest 280x so i'd go for that for maximum savings. Otherwise the Asus has a very good cooler and gigabyte, MSI and XFX are all good too.
Also I agree that upgrading the motherboard is not a bad idea, but at $35 off, the Gigabyte you selected is excellent value. Upgrading the PSU if you think you will Xfire/SLI in the future is a good idea, but if you don't really think you will do it within the next two years than I wouldn't bother as by that time you'd probably be better off with a new card.
I personally don't like SSHD's and would rather separate drives, but thats really up to you. Some people love them, some don't.
1. That is not quite correct. The fan controller is the only fan controller that uses a PWM signal to control 3 pin fans saving $5 or more per fan and eliminating annoying PWM motor humming, buzzing, ticking. Best of both worlds situation .... all of the advantages of PWM and none of the disadvantages. Or you can also use it on any of the chassis headers. Not to mention it comes with the case that's been awarded "Best Case of 2014".
The MoBo comes with at least 5 fan headers all of which have speed control thru BIOS / utilities giving you 1 CPU and 3 or 4 separate chassis channels.
CPU_1 Fan Header goes to air cooler
CPU_2 goes to Fan PCB and provides PWM control of all case fans if ya like that option
That leaves 3 or 4 headers / channels free depending on MoBo. With just 8 fans on the 200R, you don't even need the controller... The MoBo alone is quite capable of handling all of them.
2. The Saphire coolers run about 37 dbA ... the MSI runs about 29....almost half as loud.

3. Given the budget restrictions, before I'd invest $100 in an SSD, I'd put that into a GFX card upgrade.....I don't love or hate SSD's or SSHDs but unless benchmarks factor highly into decision making criteria, with just 0.9 seconds difference in boot times between the two, if budget is limited, the extra expense is hard to justify. We have two machines here, one with a 256 Gb Samsung 840 Pro and 7200 rpm HD and the other with the 7200 rpm SSHD and no one can tell them apart.
