Best home PC build under $5500 with an SSD?

So, I'm looking to put together a home PC that can handle just about anything...
My budget is around $5,500—not including the monitor, keyboard, or mouse—and I’ll be paying cash.
I've been browsing Craigslist, but I figured it would be smarter to check in here before I pull the trigger.

1 x Intel Core i5-6400 (2.7GHz, 6MB,LGA1151) box
1 x Crucial DRAM 8GB DDR4 2133 MT/s (PC4-17000) CL15 SR
1 x MS Helios 3 Case, black, 1x12cm+1x8cm fan
1 x Fortron Hyper 500W, 80+ - 60mj.
1 x HDD Seagate Barracuda 1TB, 64MB, 7200rpm, High-Performance
1 x SSD AD 120GB SP550
1 x XFX AMD Radeon RX 470 GDDR5 4GB/256bit Single Fan
1 x ASRock H110M-DGS, s.1151, D4, S3, U3, mATX

Total: $1835

Best Buy

I suppose I'm looking at one Intel Core i5-7400 (Kaby Lake, 3.0GHz, 6MB, LGA1151) retail box.
I’ve got one Asrock LGA1151 H110M-DGS sitting here.
I've got one Gigabyte GF GTX 1050 Ti OC available, featuring 4GB of GDDR5 memory.
I’m looking at a single 8GB stick of Crucial DDR4 RAM, clocked at 2133 MT/s (PC4-17000) with a CL15 latency, single rank.
One Fortron Hexa+ 400W, 80+ unit.
I've got one 1TB Seagate Barracuda hard drive here, featuring 64MB cache and running at 7200rpm, which I'd classify as High-Performance.
I’ve got one ADATA 240GB SP550 SSD sitting here.
I’ve got one GIGABYTE Mid-Tower ATX case here—it's the GZ-IF238R model with an ABS and steel build. It comes in Black and includes two 120mm fans.

The total comes out to $5,472.06.
I suppose there isn't much to say about Futura-it, though I guess I could attempt to weigh in on it if necessary. It’s just one of those things that sits there, neither particularly remarkable nor entirely useless, I suppose. Maybe it serves its purpose for some people, but from where I’m sitting, it doesn't really jump out as anything special. I don't know. It might be worth looking into more deeply, but I haven't found much reason to dive in just yet.

They're both decent, but even though the one at Halekova has a bigger SSD, the Flatronov model has better graphics... so I'm thinking it’s the better bet for gaming.

Skylar, I wouldn't spend those extra bucks on Katy if I were you...
