Can any recommend a good&inexpensive rack mount case for mining?  (one that can obviously be well cooled).

Ended up with one of these: http://www.directron.com/cs4801.html?gsear=1 (Seems very similar to that codegen 4U-600)...had to remove the 3.5" drive rack to make room for the GPU card, but I didn't need it anyway and it's better without it since it was between the fan and the GPU card.

google codegen, see their 4U-600 cases. I use them, good stuff.
Do you have any pics of what your rig looks like on the inside of this case?

None of the 4U rackmount cases I've seen are space efficient at all unfortunately.

With a standard 4U rack you can easily fit 2 motherboards (with 4 cards each) and 2 PSUs if you just leave them on a tray.

The whole point for a rack mountable case, is so you can mount the cases in a rack. I want to be able to mount 10 4U cases in a rack. You can't colo motherboards on a tray.

"space efficient"
Who cares about space efficiency? The only thing that really matter for mining is cooling ability (IMO).

Trying to colo with a rack will kill yiou price wise. Seriously Wink Colo power is not cheaper than at home. On top, most colo do not hadnle the power usage. FOr example my Colo is limiting me to 20 ampere per regular rack Wink High power racks go to 40 - for 1500 EUR a month for the actively cooled rack. Power extra.

THink you get flatrate? Sure... for like 250 watt power consumption for a case. Nice, but not suitable for mining.

That said we are just planning a 5 rack units case for 6 cards, possibly 10 (for a long version). Availability within 3 months.

I have read of some people using these:

http://www.frontierpc.com/components/computer-cases/chenbro/rm41300-fs81-rackmount-enclosure-rm41300g-1019095720.html
Made to house tesla's. Now, the price seemed terrible to meat first, until I read that it includes a 1200W PSU. Now I wonder how good the PSU is, as I didn't find any specs on it.

We use Chenbro cases in our server farm. They are good quality cases. Get one without a power supply. I recommend this model:

http://www.frontierpc.com/components/computer-cases/chenbro/rm42300-rackmount-enclosure-1019095721.html

Our racks include 3x 20-amp circuits. That's enough juice for about 10 systems per rack. Cooling is provided by a Cold Aisle Containment setup like this:



Cold air in the front, hot air out the back.

What? Most data centres allow you to colo non rack equipment on steel trays. Considering that you're paying for space, of course space efficiency is important. I pay half the price per rig when I squeeze 2 rigs into a 4U rack. Cooling ability in a DC? Just let it rip with some 5000 RPM fans and not worry about the noise.

It sounds like you haven't thought this through carefully.

Is the Chenbro PSU not good? I mean, the 1200W PSU for that price in a decent case would be pretty awesome, but that depends on it's quality, of course.

The Chenbro you linked only seems to have 7 expansion ports on the back, how easy is it to "modify" to accept 4 GPU's?

I'm not in a colo but I do have a rack in my garage. I'm using these 4U cases from NewEgg.

http://www.newegg.com/Product/Product.aspx?Item=N82E16811219019

Note: the pic of the rack is prior to loading my mining rigs. Maybe I'll take a pic of it later, but the rack is mostly full now. If you're in SoCal and need a rack, I can get you these Sun ones for $250 including 220v PDU C13.

I considered that case but the problem is the cooling sucks. Don't buy if you run more than one card. Cooling is KING!

Well if he has his rack in a basement or unused room there is no reason he couldn't slam a 5k rpm fan in the front and one in the back. I'd search on ebay for some of the metal fans the old HP servers used to use, those things never break down (had one running in a data centre for over 6 years solid, never been turned off).

Nar these where huge 120mm black things with no guards on (Back before H&S went mad...I mean come on who in the right mind puts their finger into a 5k fan).

$20 from Vibrant, tempted to grab a couple actually. Thanks for the link

I think I remember the fans you're talking about. I had a large Compaq DB cluster box (where two servers were combined with attached SCSI storage) that had big black metal fans inside.

I just picked up some more of these Deltas. 240cfm for only ~60dB. http://www.newegg.com/Product/Product.aspx?Item=N82E16835213001

Is it possible to use risers in the pci 1x slots in a 4u case? I've never seen a 4u case in person so I have no clue how big it is. I understand you can fit big cards and most cpu coolers, but is there enough space to mount cards on a riser somehow?
