[Guide] HP 6300 Pro / HP 8300 Elite - A 100 percent Working and Easily Affordable CustoMac

I'm in the UK. In case you missed it, I edited my post above with more info.

Isn't that image of the CMT?
MT = Microtower
CMT = Convertiable Minitower

What matters most now if I can make the RX570 or RX480 fit inside.

You got the right one then. In the USA only the 6300 Pro Motherboard goes into that smaller mATX size MT case. 8300 Elite boards go into the tower "CMT" case. You'll just have to live with the smaller amount of room you get in contrast to the 8300 CMT. At the US Ebay site every MT or MicroTower has the 6300 Pro board.

Thanks everyone.

I would have got the CMT but they don't fit under my small desk space but the MT does just fit.

As long as a big graphics card will fit everything will be cool, any idea if it will?

Is the motherboard the same as the SFF, hope not as I wanted two quick SATA ports, but it's not the end of world if not?

@trs69 I'm currently struggling with installing Catalina over on the Catalina thread, are you able to assist, please?

 

[MrNeedSomeHelp]

Due to the space concerns in the MT case, I'm looking at ITX cards, will this card work with Catalina please?

the other option I'm considering is using a pcie riser cable and mounting a larger card (480 or 580) to the lower section of the case (isolated) and routing monitor cables out of the case via the empty slots. The main benefit is cost-saving from this method.

Yes

Yes

The RX570 itx arrived today, its a 6 pin connector and requires <150W. Its recommend I use a 500 Watt or greater power supply. I was thinking about running it on Pcie power for now, is this safe?

I also need a little help selecting a new power supply and adaptor cables.
Any recommendation welcome, thanks

It's recommend I use a 500 Watt or greater power supply. I was thinking about running it on Pcie power for now, is this safe?

It won't run without the 6 pin power connected. You could hook up 6 pin power adapter from the motherboard directly if you can't wait to use it. On a side note, I run a full size RX 570 (8 pin supplemental power) off a 400W PSU and it works fine.

One of these from EVGA will get the job done for you. Not too expensive compared to most PSUs these days.

Help needed, I am trying to install Sierra on my hp8300 SFF and have for the last couple of hours followed the guide to the tee but am stuck here and never get to step 7...
"leave your Unibeast drive in the USB port, reboot and select your Sierra Hard Drive (HFS) and finish the setup."
After selecting the Sierra Hard Drive I see the Apple logo and a progress bar that stops at around 70% (there is never any text of finishing install) and a small line appears on the screen and it systems seems to be frozen.
I have reset the bios, carefully made all the necessary changes and tried again and again...
Is there something I can post to give anyone a clear insight into my system/progress/error?
