Affordable Multi 4K Monitor Graphics Card for your HP Mini-Tower
These are selling for $69 dollars right now on Ebay. Note that if you have an SFF HP desktop there is no LP bracket included. These are Kepler based and should work well with the latest macOS Mojave. No drivers to install.
This is the only way I know of to get multiple 4K monitors working at 60Hz. You can have up to four but I'd guess that would be pushing this card to it's limits. Dual 4K monitors connected to your HP MT would be perfect. Three of them would work too. There are many good 4K monitors now that sell for under 300 USD. Try Amazon and Newegg.
Don't expect to game at 4K with one of these cards. They are not designed for that. Photo editing or CAD works fine. Remember the 2013 Mac Pro ? The AMD FirePro cards from 2013 were absolutely terrible for gaming, even if you ran Windows via bootcamp.
Amazon Basics has a miniDP to DP cable that only costs 8 USD if you have multiple 4K monitors (not TVs) So to connect four 4K@60Hz monitors will only cost 32 dollars. Not bad.

Mine came with a LP bracket and I bought a full size bracket from AliExpress - so they might have the LP bracket as well.
If anyone finds a replacement (no fan) heatsink I would be very interested. Thats the only reason I'm not using my card in main machine, as I like quiet computers!

True, the fans in these are too tiny to be quiet/silent, they spin too fast. I'm sure there is some kind of passive cooling solution that would work. It looks pretty simple to remove that plastic shroud. I would also put new TP on it to help keep it cooler.
Quietpc.com says that the fans are very quiet. It's likely that they tested a new one. Once they are five years old or more the fans probably get noisier due to dust and wear and tear on them. The lubricant tends to dry out too.

What it would take is a cooler like the NVS 450 has. Obviously one of these wouldn't work on the 510 model. Much too big to fit.

@trs96 thanks for the links. I have seem someone who took a heatsink and cut it down and drilled the correct spacing holes and they reported it worked fine. But I would rather something off the shelf / easy to mod.

It may have been "quiet" to start with, but I guess I am perhaps stricter than most. Ideally would be running a passive PSU (if it fitted in the 8300) and an aftermarket very quiet (120mm low rpm fan) cooler - if I found one that fitted in the 8300 CMT. With an SSD as the drive that should be inaudible under my desk.

From the way the NVS 510 looks one of these Asus EN210 heatsinks might do the trick. I haven't got a Quadro card to test it but it may work. These 210s by Asus are easily found on Ebay. I don't know how tall the capacitors are on your 510 but this looks like it might fit. EDIT: Looking at the existing screw holes in the PCB more closely, you might only get two of them to line up so it wouldn't be seated on tight enough. Probably not a good idea. Why not just take the plastic shroud/fan off your 510 altogether, leave on the existing metal heatsink and direct a silent case fan right at the card ?

Hi. Thank you for the guide @trs96

Any chance for guide install HS/Mojave on HP Z220 CMT (Main chipset Intel C216, Intel Core i7-3770)
Because i see that HP z220 CMT have more rooms for PSU, Disks, more size for VGA, CPU heatsink 4 pin..etc..? I've installed mojave on Dell 9010 MT, but its seem to lack space for more parts if you want to upgrade. And the price is the same at Dell 7010/9010

The Dell Optiplex you have is called a MT but it's much closer in size to a microATX case. The HP 8300 MT is about the same size as the Z220 you have pictured. Some people have had success with the Z220 and you can use this guide if you get one with the i7-3770. Not sure if the install on a Xeon based Z220 would work the same. You could certainly try that if you need a Xeon for some reason.
 
@philipstonybi how many extras do you want? The HP8300 CMT looks very similar internally (if not identical?).

Yeah, but where i live, they don't sell HP 8300 CMT :( , and HP z220 ischeap, about: 180$ for i7.
If i build HP z220 CMT, then i can have more ssd/hdd, RX580, WIfi adapter ...ect
 
then i can have more ssd/hdd, RX580
If you want the RX580 you would still have to upgrade the PSU and use an 8 pin power adapter from the replacement PSU. I don't think the Z220 PSU has an 8 pin supplemental power adapter to connect to the RX580.
