Well done! Possibly the best 800 G1 case swap video I have seen yet.

[@fulltrottle8856]

Really like your explaination.. very detail that all i need.. thank you sooooooooo much!!!!!

[@christianmino4073]

Well, that’s so funny I thought I was the only person to manufacture of my own little wingnuts out of those ribbons they gave you lol for the CPU cooler

[@christopherlongo3459]

Great video I was able to do the case swap without issues Great work with the front pin headers on the board 👍

[@TechRoundUp]

Glad it helped

[@trevorspcs]

@@TechRoundUp do I need an hdd because I don’t have one

[@knk4736]

Does this work with HP elitedesk 705 ssf?

[@carbullzone953]

Im looking to do the same but with an hp 8300 sff. Great work.

[@DLMtechgarage]

I did a video too on doing the case swap. Bypassing the front usb errors are real easy to do, just a matter of jumping or adding a ground. Will post a link to the video I did explaining it. Love the content!!

[@christopherchristiaan3788]

Your videos are awesome, i will do the swap using your method this month, will try to at least send pictures when its done

[@christopherchristiaan3788]

Thank you for your vids

For the psu, u can make an extension plate out of metal attaching the case screw hole for the psu and the screw hole on the actual psu

[@christophergameing5175]

or 3d print a bracket if you have a 3d printer or know a friend with one also 3d print a io shield

[@RobBroderick44]

I'm on the process of doing this swap, but on the TWR model. Finding #6-32 x in huts for the CPU cooler here in Europe his a huge b*tch, and I don't see myself butchering the old case to get the tabs. But I don't despair, I'll find a way eventually.

[@jayczi6713]

Hello again sir, I was curious wether the tabs for the cpu cooler would short anything out?

[@heyrob5900]

Is a G2 sff pretty much the same process? Want a new case and to upgrade the PSU

[@antoniskourtesakis2127]

i will do this for sure, but at the big empty area I will put pop Funko God of war and last of us, and i will also put led light strips make it even awesome

[@JohnPaulBuce]

thank you 😍

[@theobgyn6787]

Why use the T400 instead of a 1650 LP? I'm not too familiar with the T400s though...

[@999ZZZ36]

Hi Mate, I have seen alot of there Vids about the Prodesk. Could you move the CPU to a different system. I heqard HP has a wierd lock on it? can you confirm?

[@trevorspcs]

can you use the same parts but swap out the motherboard with a new or do you have to get new parts

[@FL0Valo]

Is it an option to use the master box 3.1 lite instead of this one? Because I couldn’t find one 😢

[@trillasosa_]

what is the screwdriver to remove the moverboard screws???

[@lattaem]

very helpful video! my only concern is not having the same pc. i have an hp 8300 elite small form factor. how do you reckon finding a case that fits?

[@mizu5521]

same thing really i have the same pc and its a mini atx motherboard so youll be okay

[@stopikitzy.]

how do i know if the hp elitedesk 800 g1 sff motherboard is compatible with normal micro atx cases?

[@DefaultLynx]

But how does the small form factor mother board fit in the large pc mother board spot

[@ernanfer2]

I'm going to do it...but I change of the cpu fan(rbg) change de psu, I send to print a I/O shield backplate in 3d and other things

[@LoveForTheOutdoors]

Can you do a case swap for the elite desk 800 G4 sff

[@ubaydcarra8411]

Where do I put the USB cable in the motherboard because it doesn't work when I press f1 on my keyboard

[@seriksson9721]

Bravo bravissimo fantastic, just like you should do if it is to be cheap and good. Many thanks.

[@gnawt]

yeah thst power supply isnt going to cut it for graphics cards, id upgrade to a 500w or 600w

[@EdgarOntiveros-nh9ot]

The easiest swap you can do is hp pro 3500. Everything connects right even if you swap the power supply for a bigger gpu. No errors

[@TMPBrickzz]

Where do you plug you're case fans into

[@christophergameing5175]

does thiis swork with 800 g2 sff as i wana upgrade the case to a bigger office pc case with alot more airflowand upgrade the gpu from a 1030 to a rx 580

[@Celluarexpress]

Do you like I got mine for like 30.. mine has the laptop ram the sodiums... Allison do you need to fin d a good mxm gpu

[@iannene750]

does the 800 g1 have a hdmi port? and does it allow ethernet only for internet?

[@seanDunne-xt9je]

Hey i really want to know if this will work on a Hp compaq elite 8300 sff

[@musicforyou1464]

Cabe una gráfica grande de 2 fan? O solo pequeñas de 1 fan?

How do you remove the graphics card bracket

[@cleitusmichelo3805]

bro i have an hp 290 G1. i already have a GPU and everything works well i just hate this small case what can i do?

[@Momo-ei6cr]

no thermal paste on the cpu cooler ?

[@imraansy11]

Hi, can u please let me know where can i buy similar case

[@PynixyVT]

can any power supply work? for the swap

[@amoslaton437]

What nobs did you put under the cpu cooler that you screwed under the motherboard

[@fluxs]

I have a elitedesk 800 g1 tower, so the power supply is much bigger than the sff u have but other than that everything else looks the same, this is my first pc so I was wondering if I should swap the tower into the micro atx case u got in this video or if I should have a different case could you help me out?

[@RobBroderick44]

The 800 G1 TWR's mobo fits perfectly into a MATX case. Get a regular ATX PSU if you can too, as the OEM's screw holes don't line up with the regular ATX mounting ones.

[@lom2969]

Hewlett-Packard HP ProDesk 600 G1 TWR which wire to buy I can’t understand 3 or 4 wires need sorry google translate

what case did you use?

i want to know a cooler that i can youse in this motherboard , because i bought this motherboard

[@jenniferdardis2134]

what power supply and cpu do you recommend for upgrading this PC? I am looking to move it but would like to upgrade the power supply and CPU. So any recommendations would be great!

[@DragonlordXV]

corsair cx 650f 650w bronze

[@Urkayproducer]

heyy can i change the case of my hp z2 g4 ?

[@AydenC1248]

I have the exact same thing as you did all the steps right but now every time I turn it on it gives me the boot message

[@ozlem_9678]

is the pc good?

[@GamerDude44]

Wheres is the video when you upgrade the power supply?

[@johnringgold3036]

FYI i tried running a fan splitter from the CPU fan header as well on this system, the power draw from all the fans fried the mobo.

[@TheUnchosenOne]

damn, good to know!

[@es1alexlopez]

So would you recommend getting a 260W Power Supply when making this build ?

[@sandm4n]

Thanks for the heads up.

[@johnringgold3036]

@@es1alexlopez yes but I wold also recommend running additional fans off Sata power adapters instead of the mono, they will be louder and have not pwm.

can this casing work for my pc??

[@dominictorres737]

So I have a case already and a motherboard because I was going to start building a PC a few months ago. Should I do this process if I am on a budget?

[@MultiColouredVagina]

Yes go for it! It's so rewarding and there are plenty of budget options. Just be patient and don't rush. But most importantly, have fun!

[@amoslaton437]

What 4 tabs you put under the cpu cooler I need to get them what are they called

[@TechRoundUp]

I used some metal snips to cut away the tabs in the HP motherboard tray. This of course does render the original case useless

[@commandocletus9914]

6-32 nuts from ACE hardware will secure the cpu cooler perfectly 🤟

[@AydenC1248]

Yo bro how big of a gpu can you through in there without javeing to upgrade the psu. I bought a full size 1650 and now iam stressed tge psu won't be enough.

[@TechRoundUp]

If the card doesn’t require any external psu power(6 or 8 pin connector) you should be fine

[@AydenC1248]

Bet thanks cause spending 400 bucks on the gpu and it not working would suck

Can you add a rtx2060?

[@calebhenderson2156]

@@Harmansnation hey dude. I used a Rosewill D100 off Amazon for $50 free shipping. Best case I've bought for that price. It's its $60 or below it's a decent price since it comes with 4 rgb fans with a rgb controller.

[@craigturner7323]

Please can someone reply to this I was wondering is there any sort or way of tricking the computer into thinking the USB and speaker slots are in use so the PC will boot normally

You can always keep the speaker and reconnect internally, the usb is a little more difficult

[@choppergirl]

OMG the hard drive bays on these are absoltue aweful. I don't know how you can scr33w up a 5.25 and a 3" drive bay but HP found a way. You can forget the traditional mounting via 4 side or bottom screws.There is no way to mount either drive in here without them flopping around. I finally just shoved a drive in there floating around and used foam to keep it from rattling. And opening the case was infuriating as well. Instead of two screws on the back, there is a handle you have to pull up and yank on the top cover of the case. WTF. seriously. WTF HP. PC techs do not appreciate change. Or non proprietary connectors. I would say, avoid these machines, even if theyseem like great buys. You can't put a ful height GPU in them, and the power supply is propreitary and only 250 watt. They are not as awful as Dells or Macs, but they are not much better either. I unfortunately bought 4 of these machines to give away as Xmas presents and am regretting it.
