Had some parts in the stockpile, and combined them with some new and used parts to get something useful (I hope).
Card Reader - pulled from a build I did for a relative a while back when they decided the didn't use it enough to justify having in the case. I was like, "Well, don't chuck it! I'll find a home for it somewhere!". And so I did.
Fans - The TriCools I've had in the spares box for a few years; I bought a few when they were on sale cheap, and these were the latest to find a home. I've used the others to rescue various builds over the years. The Corsair I got because I wanted a PWM fan for the PWM header, and I'd already used my one spare in my game PC.
OS - I have this, but haven't installed it yet. Bought for a build for a friend, then they changed their mind and we put Win 10 Pro on instead. Right now I'm testing Elementary OS on the box, just to see what it looks like.
ODD - Because I had it, and installing it keeps it out of the landfill (and it still works).
Power supply - Bought for another build, put aside as a spare when the owner decided to go with a bigger one right from the start (along with a better card)
Case - I'm the original owner. I bought it years ago to stuff a very noisy gaming build into; when I swapped that into a newer case for my godson to take to college, I kept this one.
Video card - this is actually a PNY single fan 950, but I didn't find a listing here and this looks the same and was about the same price, so I used this listing.
HD - I had bought 3 of these on sale a few years ago to have as replacements / upgrades / expansions (just like a lot of you out there, when the family computer takes a dump I get that call or email); got 1 left now.
SSD - Bought this to replace a Crucial M4 that had to be sent back for warranty replacement just under the 3 year mark; I'd had good luck with the 128GB version so I thought I'd try this. Well... Crucial honored the warranty, so I kept this knowing I'd find a use for it some day.
RAM - Left over from an upgrade on a 2-slot motherboard. Works well and clears most aftermarket heatsinks.
MB - Bought on sale. Runs ok so far (I've usually had good luck with MSI). BIOS isn't UEFI though; means I can make it a Linux box and not have to remember to turn Secure Boot off.
CPU Cooler - The sharp-eyed will note that the first cooler in the pics is the Antec Kulher 620 AIO. Well, because of the support rod in the case, and the fact that the power supply fits in right on top of it, I couldn't fit the radiator in the rear fan mount. So, Plan B. I had an extra on hand as a cheap, quiet, effective replacement that would fit most prebuilt systems, so I used it here.
CPU - Bought on sale as a spare to get my game PC back up on a temp basis or checking a motherboard. It's been sitting for a while though and even if it's an old chip, well, it can still be useful. Even if I just use it to try various distros or Win 8.1.
EDIT - I see a lot of builds in old cases here where people don't bother to do any cable management because the case was designed before cabling tidiness became a thing. I'd like for people to see this build and realize that there are ways to do so even if the case wasn't originally setup for it. Comments are welcome.
