The Wolf in Sheep's Clothing
This thing is like if you threw a V6 turbo engine in a Mazda Miata. Runs VR like a champ, and AAA games on mid-high settings at 1080P look amazing. Would have broken hearts and blown minds circa 2017.
The outside of this Optiplex 7050 case is a mere shroud to hide the serious fangs of this build. Like the demon of Babylon hiding in the coat of the righteous, even the inside seems unassuming and rather lackluster. But for those who care not about brute force of PC's ten times the price, this stealthy competitor holds it's own. With a total cost of $310 to raise this Lazarus of PC's from the bargain bin to the arena of gaming, there's no doubt of the value for output for such a reanimated creature.
This thing hangs out with builds triple it's size physically---the Small Form Factor case and 9lb weight making this lightweight all the more deceptive. Running off of the thin meager sustenance of 180W, it performs to par with PCs with PSUs 10x that wattage. The GeForce RTX 3050 only draws 70W, sacrificing no performance in it's grinding sprint of raw gorgeous output. Ray Tracing in VR never cost so cheap and required so little.
Is it stuck in Windows 10 Pro cause of the CPU? Yeah.
Does the GPU fan howl? Yeah. But that's how under this sheep's wool, you know this wolf is still alive :)

Theatrics aside, this was a really fun PC to build. There are SO many constraints you'll face if you ever try building a mid-tier gaming PC out of a SFF (Small Form Factor) office pc. Wattages, physical constraints, and compatibility issues make up most of 'em. Finding parts that fit the case was so annoying, but part of "the game". The Optiplex 7050 I picked up for $25 with working SSD, 16GB DDR4, and a not entirely horrible CPU (i5-6500). It came with a NVIDIA Quadro K1200, which had surprisingly good performance for a 4GB card from 2015, but I knew for more intense stuff, It wouldn't cut it. Finding a good GPU was paramount, as the onboard graphics are... definitely not enough for anything I had in mind; VR was the end goal, perhaps originally optimistically. While the Quadro K1200 COULD---by a miracle---run VRChat, it would start to throttle quite seriously after about 20 minutes. Having a CPU not rated for VR might have certainly been a bottleneck too.
I came across possibly the best Low Profile GPU currently on the market, the Yeston Geforce RTX 3050 (6GB). It's realistically the ONLY decent quality GPU that will fit the a SFF case, and also required no new PSU---another component I really wanted to avoid replacing. By the grace of the Lord, the 180W stock PSU worked just fine. I found a used i7-7700 (the highest compatible CPU with this motherboard) for $50, and installed it with no issue. I COULD get a i7-7700K, but those are still super expensive for frankly not a huge uptick in performance (near DOUBLE the price... for a quad-core). I bought two more 2133MHz DDR4 8GB RAM sticks, boosting the system RAM to a nice and respectable future-proof 32GB. It's compatible with 2400MHz too, but I wasn't hard-pressed to milk the 267MHz more out of the slightly more expensive RAM of the two options.
And that's it. That's where the build ended. New CPU, RAM, GPU and nothing else. I could have dolled it up or stuck any RGB junk all over it, but I decided to keep it's biggest appeal; the surprise factor most sleeper builds have. It looked the same on the outside, and even on the inside, you'd be hard-pressed to notice any difference, minus the bright pink shroud of the GPU. In regard to performance, it gave me all I'd wanted and more. It runs VR at 90FPS, and with a Oculus Quest 2 Airlinked to it, it's all I dreamt of. Yeah, it's loud especially when running modded VR, but given the price of the whole setup for such little input, it was worth it. I came into this with zero experience in anything PC, and I'm happy to say I learned a lot from this process.
If you're not doing anything VR for gaming, I'd still suggest simply get an Xbox Series S. 120fps 1440p and upscaled 4K for $265 is such a deal (at least it was in 2024, idk what it is now). But for multitasking and fun stuff like VR and rendering, a small DIY build like this is the way to go. Proud to have made this, and I hope this build inspires others to make the most with the least!
