I got that VS450 for the equivalent of $30. Also, that Carbide 100R for $35. The case is surprisingly good for an entry-level Corsair.
Yes, those Corsair cases are great for the money. Was looking at them for a low profile build for a friend in a few weeks. (Gonna be bumping to a TR 16core ES/mATX build in May-June) I just retired the Thermaltake Element V "TPU Review Sample"(Hai Peet!) when I went to the Corsair 570X.
I got my Seasonic X Series 850W KM3 for $72 brand new, warranty and all from Newegg in Nov 2016. Forgot to send in the $20 MIR though. lol. I guess miners screwed up the high end PSU market too. :-(
I have a few SS-550HT OEM "Retail-Pigtail" units still on the shelf that I sell at my shop for $30. You can get them on e-bay here for $20-40 still. But my gosh are they reliable and can take a beating. Most are 650W units just branded 550W. Used that PSU for 3 builds over the course of 8 years before I retired it to a life of... ease... powering a 780Ti in my neighbors rig.. lol. That thing would be pulling 700W from the wall and still keep 11.98-12.02V.

I feel bad for you Harvester.. :-( GPU market is still in shambles. Prices are coming down though. I have seen a few RX Vega56 and 64 cards in the 700-800 range. Which is still not a good deal. (Think 400-450 for V64 air cards, 550-600 for V64 water cards) Your CPU is fine imho if you game at higher resolutions like 1440p and 4K. Looks like a fine build though. You take care of your equipment it looks like.
