He didn't list the motherboard so I'm going to guess it's an non Z board. So I personally wouldn't go for a K model unless it's about the same price or less. So if he wasn't going to upgrade anything besides the CPU I'd say buy an i5-6400 or i5-7400.
If possible I'd wait till you have more money since your going to want to do a full upgrade some time soon anyways. That way you don't waste your money doing a small upgrade on your current system which wouldn't be able to be brought to the new one and you can then put that money towards a getting better parts for that new system. Other wise like I said above I'd go with an i5-6400 or i5-7400 with whichever is cheaper being what I'd buy since there isn't too much of an improvement between Skylake(6000 series) and Kabylake(7000 series).

@UnSimpleCurioso The ViewSonic TD2230 seems to be a good monitor for your needs. It's 22" 1920x1080 60Hz IPS Monitor with according to this review has a response time of 7ms and has good color accuracy. Also right now it can be found on Newegg for $250

@exon654 ^ but you should also while the USB drive is getting setup or at least before you install windows make sure everything is detected properly in the bios.

Another problem is that Chrome OS relies on internet access for it to really have any function since most things would be in the chrome browser. So of course this would go against the fact that you wanted it to not have internet access

Have you tried looking into PCI-E to USB 3.0 Header Card

@xtrathund3r This should work really well for your budget of $800 - $900

Yes 

I looked it up and you have to redeem the code TES25TH-MORROWIND on Bethesda's storefront

Maybe use that space for a personal media server and I do agree with @Lurick that you shouldn't sell that space

@KingNets Check your drivers if Slottr isn't able to fix the issue since I've had a problem one time where the drivers for my RX 580 caused all games to feel like the game was lagging till I went to a previous Driver Version

The only one that is $320 is the MSI with a blower style cooler and that one is the 2nd cheapest with the 3rd cheapest being the Asus Strix model for $380. Though if you don't care for DMC 5, RE 5, and the Division 2 I'd at that point go for an RTX 2060.

if he was to go brand new i would rather pick up a 200ge for the vega 3 igpu
 
but used exists, get a nice optiplex or other older machine, slap in something like a used 390x or 970 and have much more fun

If you're going for high refresh rate gaming then upgrade the CPU. If you're going for high resolution gaming upgrade the GPU.

What is your budget and what do you plan on using your system for?

What resolution and refresh rate are you playing at?
 
The 2700X will be better for streaming as it has 8c/16t and the 9700K only has 8c/8t.
 
You could just get a 2600 for now and sell it later on and replace it with a Zen 2 chip that will have more cores and be on par (if not better) than what Intel currently has.. Making it a bad ass streaming and gaming machine..

I would put my CPU in and try.
 
Nothing can go wrong if it doesn't have the update.  It just wont post.

Yes, this CPU doesn't have iGPU meaning that video output ports on the motherboard are useless with it. If you're looking for a Ryzen chip with integrated graphics, the best one currently is the R5 2400G.

No ALL Ryzen chips are overclockable as long as they are paired with a B or X series board

yep   
the only thing i would do first, is unplug the old drive before starting the computer at least once, to make SURE you are booting off the ssd. then plug it in and wipe it
