Do you think it's better to do the installation yourself or go to someone?

Rackmount cases normally cost more - they need more stable material than normal once.

I get one for 12 cards in hopefully a week. On 2 boards, behind each other. That is 12 dual slot cards that live on extension cables and are decently switched Smiley 5 units high, cost around 250 USD.

got a link? That sounds awesome!

he's having it custom made. btw, it's cheaper to just get two 4U cases for $50-80/ea than get a dual MB case for $250. Unless there's something I'm missing?

Maybe it's a small rack. Sounds awesome regardless. =)

Are there any rackmount server cases out there with 8 expansion slots for under $100? I've been looking for months... =(

I personally dont think this isefficient.

I am just getting drafts for my own custom case design that will:

* Carry 2 motherboards, 4 PSU, one behind the other.
* Be 5 Rack units high.
* Be totally optimized for airflow
* Carry 5 (!) cards per motherboards on extension cables.

The goal is a 40 double wide cards per rack design Wink

Setting up some mining operation at the moment - I order teh stuff half rack wise (40 cards) and I dont want to spend too much for rent.

That is quite an interesting case idea. Now, just how much does it weigh and what are you mounting it on - rails? tray? Pics!

I expect the drawings today. Rails - probably now, bu tthen you can buy some metal rails for rack cases. I will put up drawings and pictures as I get them. The specs say 100 cm deep, 19", 5 RU Wink So, it is perfect for 16 systems per rack Wink Custom made, as I said - price indication is around 200 EUR Wink

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?

If you look at this picture of my 4U case you will see that it is not really possible to do so unless you managed to rig up some kind of card holder but even then you only have about an inch or so between the current(stock) level of the cards and the case lid.

If you go with single slot 5770 or 6870 cards you can do 4x density in a 4u case with a Sapphire PureBlack MB like the one here.


Cool thanks for the help makes sense.

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

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).

You mean these?
