Hi Dave, I'm interested to know why you say "a better heatsink - Of Course." Surely the stock heatsink is adequate to the task.

Probably, but I've heard they are noisy, and that pretty much everyone replaces them.
I'll try it though.

It seems a bit of overkill to me. Where are the resource needs for live streaming coming from?

Full HD Compression + saving to HD in real time, + the streaming feed (perhaps to multiple servers), + live video view, + playback video view
Current Q6600 PC is running 98% CPU usage and seems to be dropping some audio.

Actually, the stock heatsinks are pretty shit, and pushpin mounting is awful. Under heavy load the CPUs get very hot, very fast, while making a lot of noise. Nehalem is not a cuddly low power architecture.

Good heatsinks are cheap.

Dave, get a Hyper 212. Not many better heatsinks and certainly none with a better price.

To echo what Monkeh said, those Intel HSFs are deafening even at low speed, and not very efficient. I had a cheapish heatpipe HSF which I used on my old AMD X2-3800 which (with the supplied adaptor that I had miraculously kept!) does a much better job. With all 4 real and 4 virtual cores saturated it goes up to 70C or so, but at least I don't have tinnitus after 5 minutes running!

Before investing much money though, I would check the CPU and motherboard actually still work. Stick the HSF back on and plug it into a 400W or so PSU. Even without a graphics card it should still beep several times if the CPU and motherboard switching regulator works (if the mobo has an onboard sounder) but it will need some memory in those slots or it may not even attempt a Power On Self Test.

Wilfred, aftermarket toner is plentiful for big HP printers, and there is a strong market in things like fuser rollers etc. I think this series of printer is around 10 years old now, and the Chinese third party sources are well up to speed. Big battleship-built workgroup printers like these made their money for HP right at the beginning, unlike consumer gear which screws you for the toner. First hit I got on Aussie Ebay for black toner was $89 including free postage for what seems to be a genuine HP cartridge (6000 page capacity) from a big store.

I got a big printer like that from a surplus auction recently.  I bought a whole pallet of printers for $10, but the nicest and biggest one is a Xerox Phaser 6300, and I think it is even bigger than your HP.  Probably a bit newer too, because it actually has a network connection, in addition to USB and parallel cable.  You mentioned maybe they got rid of that HP because it doesn't work with Windows 7.  I think there might be a similar issue with mine, but we got it to work just fine with the newer operating system after a bit of tweaking.  I have absolutely no space for such a big printer, and replacement toner cartridges are really expensive.  For now a friend is borrowing it, but I'm trying to sell it.  You have to come to Oklahoma to get it!  See pictures here: http://stillwater.craigslist.org/sys/4514677408.html.

Hey Dave,
If the motherboard is kaputski, you might struggle getting a new one as intel moved to socket 1155 a few months later.  Let me know if you're interested in selling the CPU.  :D

Cheers,
Mark

For the dumpster room, maybe could try build some kind of door switch that remotely logs times the door was opened and how long it was open. Or it logs locally and sends everything every other minute or so, so it could be powered from batteries or rechargeables? Those eRic modules might be a good candidate to go through all that concrete. Also maybe log when the lights are on, and make a decision if someone dropped a huge load in there or just came to see if there are anything good. 

This as oppose to installing a camera in there.

Dave,
I have used one HP 3700 with Win7 64-bit. No problem, but slow and new toners will cost.
Use it to the toners are empty. Then return it to the dumpster.

That, that is, is. That, that is not, is not. Is that it? It is!

Dave,

FYI. In the rack mount 'server' case the Power supply goes front right and the Hard drives go back right.

Not that expensive when each cartridge yields 6000 pages, well as long as you don't buy OEM replacements :)

Correction, Use until the toners are empty and then tear it down. :)

Just powered up the motherboard and it boots into the BIOS no problem!  :-+

That is funny...you can find better a better computer just thrown away that all computers still in use in my house combined :D You sure have some nice dumpster dive opportunities there  :-+ Still wonder why was it thrown away, though.

Yep, my only faster PC is my video editing machine with the 3770K
I have a HD7850 video card for it, but probably gross overkill for this use. Might whack in an a much older fanless PCIEx16 card that is about 100th the speed.
The SSD and HD from the current streaming machine (previous dumpster dive quad core Duo Q6600)will be transferred over, hopefully intact.
It has 4GB of DDR3 memory which should be enough.

probably that i7 was a print server for that HP 3700 ? and the person ed-installing the print server was expecting some slow P4 under the heat sink and he just salvaged the ram, disks, the low profile PCI cards  and the power-supply :D

What a hilariously unlikely scenario.

Anybody stupid enough to think that had a P4 wouldn't know how to use a screwdriver.

No idea. Unless there is some other fault I haven't found yet. The RAM I can understand. Disks - maybe.  The cards - maybe. The PSU - why?
If you knew that much about PC's to take that stuff, why wouldn't you know that's a fairly modern USB 3 motherboard? Maybe they thought it was custom or something?
Will get it fully fired up tomorrow.

Most likely cannibalised for other machines and then simply discarded to make room. Happens all the time.

Hi Dave,

Have a look at vMix http://www.vmix.com.au/  for the streaming machine. I have found is uses less resources than other video mixer software. You can mix the audio separately from the video or just have one audio input etc. So no more lost audio when you switch to the microscope input. Best of all it is made in Australia!

Thanks, will check it out.
Need to try Xsplit and now this. Supports Youtube Live and my Avermedia capture card too! (but no screen casting?)
Sounds like it needs a decent video card though for the compression, so I might just whack in that HD7850 after all.
Wirecast was too many issues, and is not cheap. It's the one promoted and offered by Youtube, so I naturally tried that first.
Open Broadcaster doesn't seem to do the job at first play. Maybe it can, but not at all obvious.

If you plan to keep the printer let me know and I'll send you a JetDirect for it I still have floating around.

If you want good CPU coolers, Noctua is the way to to. Your i7-3770k has only 4 GiB of RAM? Up for 8 or 16 GiB, feels much better with Windows 7 x64. Even my i7-2600k has 16 GiB by default, I could go to 32 if I want. There can never be too much RAM.
If you want that printer go to network: Raspberry Pi + Raspbian and CUPS printer server.

Sure, they have some good coolers. They're a little expensive for how they perform, especially on a salvaged system..

That printer works well with Win7, XP and with anything that can speak HPGL5 or 6, it even will handle postscript perfectly.

Some of those used HP printers are just gems.  It can be difficult to predict (for me at least) which of the new models are going to be gems and which are going to be lemons.  When I purchased my most recent printer I went for a used LJ 4200 because of its good track record.  I think it was about $300 shipped from a reputable eBay seller with toner AND duplexer.  Yes, it's old, but even with the 70k page count I suspect it will last me a decade unless I have reason to upgrade.
