hp does stupid shit with the power supply good job. All of these proprietary connectors are a disease.

If you have a Dremel and some scrap steel/aluminum I'd suggest fabricating a simple bracket for the Powersupply. Friend of mine did that with a XW4600 with a dead PSU

Hmm good idea!

That's a good looking HP rig, wish I had the patience/skill you have at dealing with all the proprietary crap.

haha so you hacked a different motherboard into a different case. Although its all HP stuff so your warranty must still be good 😉

I've got a xw6200 which shares the same case. I like it, its kind of thin rather then "fat" like the later ones, although been duel socket I'll keep that as is.

Thanks! And yeah, the dual processor 6x00 and 8x00 series are real beasts! The Z**0 line are also really well built but also... proprietary.

I have looking at mods to bring up watts from their insufficient 400W that is commonly found in Z2x0 CMT series. (Z220 and Z230 I have).

What I need to do is use a aluminum plate counter sunk drilled so screws to hold ATX PSUs against plate, screw heads sits deeper into the counter sunk bores and threaded holes for the HP Z2x0 chassis. I have tested the "in-theory" fitting and this will work. Have to buy the plates and lay it out and drill, tap and cut opening for ATX PSU.

Second, I can use HP Z420 600W with only one mod installed in either Z220 or Z230 but one pin 16 has to be pulled out and Y-ed to the PWM signal from the motherboard otherwise fan in PSU spins at full speed. I made short adapter to extend out 8 pin 12V to 4 pin plug with 8 wires in pairs spliced very close to the 4 pin plug to cut down on voltage drop, pinout is standard ATX CPU 12V.

While ago, I built a crazy inexpensive computer planned for XP but got dis-railed based on 8300 CMT motherboard, i5-3570 , tower heatsink from HP Elite 800 G1 SFF secured with 6-32 nuts under motherboard's, which is better and lighter, quiet. In a generic ATX case. Ran Windows 10 Pro, activated using the motherboard's. Used my spare parts to complete it and ended up selling that to a coworker at work. Later on I bought few more Z series computers and someone donated a sandy bridge dell i7 computer to me. So now I have what I wanted.

you can do anything if you're crazy enough!

Sorry to bring up ancient thread. Can this case accept modern atx psu without any mods?

And I was wondering what kind of mod u had to do to make the mobo fit? If I have a small matx board, will it fit? 173x244mm

Tower 8300 only is full ATX. None smaller than this fits, the 8300 SFF is nonstandard based on BTX form factor. Next up that does work is microATX type Elitedesk 800 G1 and later but still need cravats applied to adapting it to ATX or micro ATX cases. Again same issues and needs ATX PSU harness cable adapter to use these.

Yes, you need a adapter harness with stand by voltage converter built in for standby 12V that HP 8300 motherboard requires.

Also you need to install shorting jumpers from one of ground, in the USB connectors adapters plug to prevent error which requires you to press F1 to keep going, Use SFF heatsink from 8300 SFF for lightweight and 6-32 nuts as I suggested. Front panel also need the shorting jumper too. Study the oem cables on ebay to adapt yours.

These boards has COA key already activated for windows 7 pro will work for windows Pro 10.

Be aware if you are going to use HP power supply they are 400W max or less and slightly larger and mounting screw holes are different too.
