I'm not sure if this should be here or in Build Logs, please move if I guessed wrong.

 

Last week I ordered this Dell Optlex 790 with an i7 2600, 8GB of DDR3, and 1TB HDD. 

 

Immediately after receiving it, I POST tested it and thankfully it worked. I replaced the 1TB HDD with a 750GB HDD I already had, and after changing the settings to AHCI, UEFI, and and manually typing the HDD name in, I was able to boot into Windows. I then used the included Win7 COA to activate Win10. The 8GB RAM was in the form of a 2x4GB pair, so I added two sticks of 2GB for a total of 12GB RAM.

Howd you make the circle for the fan?

I used a Dremel with a cutting wheel.

I used an aviation snips (straight) (from Milwaukee) - it's like super strong scissors. Plus a thin tipped plier to bend the metal edges a bit in order to keep cutting.

I would really like to thank the OP for posting his build. It informed me of the possibility of adding a new fan (I ended up cutting the back fan wires and splitting them so I could power both) by removing the HDD frame, but the PWM information was precious!

This computer was going to the trash bin (really) according to my (not-very-smart) former boss, so I took it, dumped the HDD, and put in a new Crucial 240GB SSD. At the time I was short on cash so simply updated the graphics with a Zotac GT 1030 - two years of happy potato gaming ^^

From the original Dell build I updated the BIOS, recently added more RAM for a total of 16GB, installed an i7-2600, and replaced the PSU with one that could provide more than 146W on the 3.3 and 5V rails (following the advice from user Speedstep on the official Dell forums).

Now I'm just waiting for a GTX 1080 to arrive  (let's see if I can still access the SATA connectors!)

Thanks, asand1 !

i don't no why the front fan cable has to go across just tune the fan so the wire at the back top...

I believe the wires you see at the bottom are a temp probe. The fan cable is at the top going into the drive bay.

Precisely.
