PC and peripherals build under $500?

Hey.
I'm looking for some advice on a full PC build including peripherals, ideally staying under $1500. I’d also love a recommendation for a shop that can handle the whole assembly from start to finish.

The setup is actually for a local volunteer fire department, so it really needs to be able to run R1 software without any issues.
It just needs to handle the basics—Word, Excel, streaming movies—plus some specific firefighting software, though nothing incredibly heavy-duty.
Thanks for any suggestions.

It’s an ASUS H110M-A/M.2 motherboard, socket l1511.
It’s an Intel Core i3-6100 (3MB Cache, 3.80 GHz) on an s1151 socket, I guess.
The AOC i2476Vwm monitor—it’s a 23.6" Full HD IPS display. It seems alright, I guess.
Genius SP-HF160 speakers, 2x2W, USB, black.
The Zalman Z3 mid Tower case measures about 192mm wide, 465mm high, and 430mm deep. I guess that's the footprint.
The Genius Slimstar 130 keyboard—it’s pretty slim, uses USB, and comes in a standard US layout.
Maybe the Microsoft FPP wireless Mobile Mouse 1850 Black paired with that U7Z-00004 SSD 120 GB Kingston UV400 could work, I guess.
The U7Z-00004 SSD 120 GB Kingston UV400, SATA3, SUV400S37/120G.
Seagate Barracuda 1TB HDD, 3.5", 7200RPM, 64MB Cache, SATA3, ST1000DM003
Maybe it's worth looking at this DDR4 8GB (1x8GB) stick—it's the Crucial PC3-17000 2133MHz CL15 model, specifically the CT8G4DFS8213. I guess it could work depending on what you need.
It looks like a 400W FSP Fortron/Source Hexa+ power supply, ATX 2.4 spec, model PPA4004900. I guess it might work depending on what else is in the build.

Total: ~$1.50 ADM offers free assembly and delivery, I guess.

I guess it could be worse. $167 It was cheaper, but I guess I ended up blowing through my budget anyway.

Am I just losing my mind here, or did you not actually install any kind of graphics card in there?

It's actually built right into the processor—you just plug everything into the motherboard to get your display up and running.

It’s built right into the processor, so I guess it should be plenty for running some lighter games 😉

It’s not really about playing games, honestly; there are these intense simulation programs they use for training firefighters—stuff like practicing how to cut through a car chassis during an accident rescue—and I have no clue just how demanding those systems actually are, though I’ve got faith in your ability to figure it all out 🙂
