here is how it looks so far. waiting for 2 original heatsinks to install teh fan box back. couldnt find any OEM  solution so far.
single 16gb ram installed. second ram in any upped slot gives error, bioas cant c it anyways. thinking of getting exact matched hp part ram set.
cant put the gpu without removing the metal thingie.

i have ended up getting case with 850 psu. now stuck at heathinks.
is the re any alternatives to expensive original (G0J48AA) ones?
thx.
P.S. have found this rather questionable alternative. dont feel enthusiastic tho:
http://www.ebay.com/itm/HEATSINK-FOR-HP-Z820-WORKSTATION-636164-001-with-Fan-647113-001-/232232385612?hash=item361220fc4c:g:Dg8AAOSwopRYmeVJ

P.S.S. ram is another point. got myself Atech 32GB KIT (2 x 16GB) DIMM DDR3 ECC Registered PC3-12800 1600MHz Dual Rank RAM Memory. with single cpu (ES 2670) post reports a ram error in ANY upper slot (5-8). modules swap ain help. similar issue could be found on hp forums using other ram manufactures. perhaps glauder could comment on this. pls share ram options who have tested already. cheers.

yeah, 12v rail, makes sence. care to share the purchase link for 1125@150ish? i couldn find 1125 on US ebay less then 350ish.
i ve foud a deal at amazon for 275USD /case+850/:
https://www.amazon.com/Z820-Chassis-Power-Supply-642163-003/dp/B018WRL6I2/ref=sr_1_2?ie=UTF8&qid=1487253780&sr=8-2&keywords=z820+power

hoping 850 will cover 2x2670/ram and single 1080.
cheers.

dear glauder - bravo and grazie!
have u considered taking that original PS apart to clone it with regular PS? i can imagine more then just 5-11v difference, so, someone tech savvy should give a try.
cheers.

Hardware projects / Z820 mobo hack. anyone?

hi gang.
the z800 mobo hack was an inspiring read. ive decided to bite a bullet and get z820 mobo. it just happens i have two 2670 (not v2) and bunch of registered ram available.
ive gone through hp papers and found NOTHING similar to the z800 pinouts posted by Andy.
there is contrary information on the hp forum: one saying the powersupply and the pinouts r identical for both z800 and z820 the other says the opposite.
so, the very first step for me is to identify the pinouts and/or understand if the z800 shares truly identical powersupply with z820, hence - i could use Andy's hack guide.
as an alternative, there is:
XXX://www.ebay.com/itm/HP-1125-Watt-Power-Supply-for-Z820-Computer-/231833368495?hash=item35fa5877af:g:bykAAOSwKtlWsKb0
and this

i have very ltl understanding of how could i utilize that power supply with NON original case. stuck it on top and hoock 1 meter extenders? weird.
looking for advise fellas.
cheers, david.
