One quirky detail of my build: it has a tiered storage system through FuzeDrive. What that means is I have an 8 TB shucked hard drive and a 128 GB SSD "fuzed" together through some old software by Enmotus that is no longer available for purchase iirc. This means the SSD acts as a cache for my huge 8 TB drive. As a result, I can just install basically any game I want to my massive 8 TB drive without worrying about space, and if I play that game more than once or twice, it'll automatically move to the SSD portion for faster access.
Some ideas:
Is this using used hardware that has a story?
Got an unusual configuration that isn't normally seen (Dual RTX 3070 for example)
My build doesn't have a PSU. Instead it has a voltage regulator. I live in an off-grid RV so my PC runs off a battery bank. There is no AC/DC conversion.
Oldass i7, 32GB RAM, couple of SSD's, RTX 2060 12GB underclocked to reduce power, no monitor since it's a VR machine/stable diffusion server. Wirelessly connects to a Pico 4.
For older hardware it manages to run everything I throw at it.
Previous build: It was 4.5L. What makes it unique is the finickiness, because it was shutting off with stock settings and it uses a Dell 330W power brick. I had to down volt both the CPU and GPU, and it worked well for ~6 years.
Current build: It's a 4090 and 7800x3D in a 10L case.
Not unique globally, but unique in my household. I have always built my own PCs, ever since my first 486. Currently, for the first time in my life I have prebuilts from Puget Systems. 3 of them, and I'm never going back.
Mine is a series of continous upgrades from my first build nearly 20 years ago. It's on its 8th mainboard generation and every part has been replaced at least 4 times, but I've never replaced the whole thing in one go so I consider it the same machine. Very Ship of Theseus situation.
I have a spreadsheet of basically every part and upgrade back to the original build.
Unrelated, I used fuzedrive with a 1tb ssd and a 3tb mechanical for a while as well. Works pretty well.
I opted to use an old Cooler Master CPU fan from a Windows Vista eMachine that I had in my home. Went from cooling a AMD Athlon X2 to a AMD Ryzen 7700X.
Having looked up the model number when building my PC, it's apparently a model that wasn't meant to be sold individually, or at least, I couldn't find any places that sell or sold that specific model previously, beyond a few old eBay listings.
May not be the best practice to re-use old CPU fans like that, but monitoring the temps when running higher-end games, it seems to be doing the job just fine!
