Who We Are: Hello! We are Lotus Computer USA, an American computer company based in Central Florida. We love to build custom gaming PCs in our workshop, and we want to share some of our completed builds with this wonderful and helpful community of systems builders.

The Build: A few months back, we were commissioned by a U.S. government agency to build 10 high-end PCs to be used in VR flight training. They sent a spec list, we made some modifications, built them all in a week, and these were the result!

Our client's primary desire was to have a top-of-the-line video card and CPU in order to facilitate VR training for their pilots. We opted to combine the powerful Intel Core i7-5930K and the NVIDIA GTX 1080 in order to meet the customer's needs. To keep up with the intense flight simulation programs, these PCs were equipped with 64GB of Ballistix DDR4-2400 RAM and a super fast 512GB Plextor M.2 SSD. We used our favorite case and favorite fan to work with, the Be Quiet! Silent Base 600 and the Noctua NH-U14S, respectively. The awesome Asus X99 motherboard and EVGA 850W PSU rounded out this build, assuring there would be lots of headroom despite the power-demanding CPU and GPU.

We were very happy with how theses turned out, and our customer contacted us upon receiving them; they were very pleased with the result and are looking to order more in the future.

Says it's for "Flight simulators" when really President Obama is having a LAN party before he leaves...

CPU is odd why the 5930k over the 6800k only major difference is number of pcie lanes 40vs 28 which woudn't matter with only 1 GPU. Unless the client specified the 5930k or the prices in the list are incorrect you could have saved $100 per cpu making you another $1000 on this project. just my opinion

We hear you, john0156. At the time of negotiating the specs with the client, the 6800K had recently been released. Their original spec sheet included the i7-5930K, which we also thought to be odd, considering the brand new line of Q2 2016 Intel units. We suggested using the 6800K (or 6900K if they wanted to get really crazy lol), but the agency wanted a more reliable, tested, and known processor; so we ended up using 5930Ks.

Never seen government commissioned builds on PCPP before. +1 :)

I work for the government. They've provided a 7 year old Dell laptop for me to work on. Now I know why. +1.

Well damn, that is an impressive story to tell... Ten PC's more then good enough for most peoples needs... Damn impressive, +1.

Thanks AnyOtherWay! I suppose when you're training pilots of million dollar planes, you want only the best of the best :)

AnyOtherWay -5 points 25 months ago

You, uhh, didn't need to include the "AnyOtherWay" in your response, it actually looks sort of dumb... Which is just dumb because of my username, but still.

Also yeah, quite true they'd want the best of the best, I suppose.

Amazing systems!!!

Thanks, Enrico411! They were certainly a blast to build and test :D

I'm going to sign up for the Air Force right now if it means I get to work with one of these.

Maetheus 1 Build 1 point 25 months ago

I would like to gently inquire as to the reasoning behind choosing the 5930K over the cheaper 5820K. The main difference between the two being the amount of PCIe lanes, and your single card solution, why would you opt for the more expensive chip? You're simply not using the whole thing. There is but a negligible difference in clock speeds. Approximately $1500 could've been shaved off the total cost of the job, by my rough calculations. And unlike john0156's suggestion, the 5820K was a verified piece of hardware.

Not trying to knock the stellar workmanship though! +1

LotusComputerUSA submitter 13 Builds 2 points 25 months ago

Thanks for the critique, Maetheus! The 5820K would have definitely been a more optimal way to go on these builds, but the government agent we negotiated with seemed intent on keeping with the original spec sheet as much as possible.

Maetheus 1 Build 1 point 25 months ago

And thanks for the thorough reply! Where I work we often get jobs making tubes (brake lines for tanks come to mind) for the government, be it for machines or otherwise, so I can absolutely relate first-hand as to how particular they can be!

Let me guess

This VR Ready PC will be used with Microsoft Flight


War Thunder :3

Do you know how much tax money we could put towards free pizza and computers!!! Who needs nice roads!!! Not only would this solve hunger but I wouldn't mind paying taxes.
