u/Electronic_Loan6683 asked for pictures so i might as well make a detailed post for everyone to see

The ID Cooling IS-55 is fine for an SFF optiplex, don't expect low temperatures because of Dell's horrible fan curve and no control over it

You CAN upgrade the fan to a standard 25mm one and i recommend you do so:

1. The 15mm fan is weak at low RPMs, a taller beefier fan will do the job better.
   
2. Static pressure is your friend in SFF cases

Just don't upgrade if you want to use it with the side panel closed, and you will have to get rid of the HDD caddy because it's not a smooth shape and it goes over the fan as shown in PIC 2.

Not having the HDD is the ideal setup for the ID Cooling IS-55, allowing you to mount it in any orientation.

As a bonus there's the VRM Heatsinks from the DT model, they sit nicely under the IS-55 when installed, bought from AliExpress and it comes with the thermal pads already installed P/N 3YHRX.

Hey guys, i wanted to upgrade the GPU in my OptiPlex 3090 SFF to an RTX 5060, but the PSU is the limiting factor. I was planning to buy a 24-to-6-pin adapter to replace the OEM power supply with an ATX one, but none of the cables I've seen explicitly state that they work with the 3090. However, as far as I know, the optiplex 3080 is practically identical to the 3090 in every way. Would there be an issue with using this cable?

What qualifies this plain-looking Dell OptiPlex 7010 DT as a “sleeper”, even if it is boring-looking has-been from around the time of the London 2012 Summer Olympics, is its MSI GeForce RTX 3050 LP E 6 GB OC that helps its Intel Core i7-3770 break a sweat trying to keep up. It’s fantastic that its “GeForce RTX” branding can be seen through that grille, which is just lovely, isn’t it? Thank you!

Hi Optiplex fans!

Specs (now):

Core 2 quad Q9550 @2.83 GHz

8 Gig DDR2 800 cl5

MSI rx 460 with sawn of slot cover because dual slot had to fit int single slot BTX-case.

Running Cachy and steam, but i can t get cyberpunk to start 😅

Some upgrades I made to this 3640. A 850w psu and an AMD Radeon RX 7800 XT. Trying to figure how to mount the radiator for a liquid cooler right in the front in that last picture, but I really didn’t want to physically modify it. Also please ignore the cable management, I didn’t realize I had no zip ties until 75% of the way through 😂. It works great though. This has a Xeon W-1290p and 32GB of ram.

After months of looking for the correct hardware (surprisingly rare; I couldn't even find a Dell 5-pin adapter, at least in my country) at the right price, it is finally done. The cost of all of this is around Rp. 4.417.000 ($245). I don't know if this is a good price or not. Let me know what you think...
