Need Help for Multi-Drive Computer Case Enclosure Setup


A

Hi everyone,

I need advice for building a case to hold all my IDE drives. I have
about 12 hard drives in external enclosures. To make space and save
power outlets I think it would be better to buy a computer case
dedicated to hold and store the hard drives. I will put about 7 hard
drives inside the case to start off... The supplies I would use are:

A computer case like this one (Rosewill R-9859 Black SGCC Steel ATX Mid
Tower Computer Case PL-300 Power Power Supply - Retail):
http://www.newegg.com/Product/Product.asp?Item=N82E16811147027
and install 3-4 additional 80 mm for HD cooling.

I would connect the two cables on the power supply mobo connector so it
will power the drives without needing a motherboard to give it the an
on signal. My friend says he knows how to set this part up (any advise
on doing this would help).

I would use a molex splitter (Converts one 4-pin Molex power connector
into four
http://www.microbarn.com/Power_Adapters_ADA-POWYX2--18-161-100881.html
) in order to have enough molex connections from the power supply for
all the hard drives and some fans.

For the IDE interface I would use seven of these USB 2.0 to IDE
adapters.
http://www.microbarn.com/ADA-UIDE--18-162-101149.html
I would connect the adapters to one USB 2.0 hub that will connect to my
computer.

With this procedure, I free up seven power outlets and turn them into
only one for the power supply. Additionally, I will only need to
connect one usb 2.0 port in order to have access to all seven drives.
And I will be able to carry all seven drives to someone elses house
with ease.

My concerns:
Will using the 300W power supply only for the hard drives via the molex
connectors push too much power to the drives causing damage to the
drives? Do I need a power supply with less watts or will it not matter?
Does anyone else think this can work? Is there anything I overlooked?

Any advise or corrections would be greatly appreciated.

Thank you,
Carlos

Why do you need so many drives ?

You'd be better replacing most of them with bigger drives,
say getting drives 5 times bigger than the current drives.

You'd be better off with true server cases with a lot more internal
3.5" drive bays if you want to have all the drives internal.
and install 3-4 additional 80 mm for HD cooling.

You shouldnt need that many.

You'd be better going to eSATA when you replace the drives with much bigger
ones.

True in spades of a couple of decent eSATA drives to replace them all.

Will using the 300W power supply only for the hard

Not if its done properly.
Do I need a power supply with less watts
Nope.

or will it not matter?

It doesnt matter.
Does anyone else think this can work?

It will certainly work if done properly.
Is there anything I overlooked?

Yep, replacing all those drives with a couple of much bigger ones.

lol thanks for your help... unfortunately, replacing them with bigger
ones will cost me too much money... they are all mostly 200-300 GB
drives... when you say "if done properly" what do you mean exactly? Are
there any tips you may have to help me set this up properly?

Thanks,
Carlos

What do you have on 12 drives of that size ?

You can get some cases designed to do what you want, a large number
of physical drives in a case with a number of IDE/USB2 converters.
when you say "if done properly" what do you mean exactly?

Just ensure that what you do to jumper the power supply
to startup properly without a motherboard is done properly.

You basically just connect the green to any black,
jumper pins 14 and 15

Just that one at the top concerning a case designed
specifically for what you want to do, a number of
drives in a case with a USB2 connection to the PC.

I'd personally have a cheap motherboard in it myself
and use a lan connection to the PC instead of USB2.

Or I could just cut the two cables, strip them, put them together with
electrical tape and use the switch on the psu for on/off...

Too crude in my opinion.

Might work.

No, you want to set up a server with RAID 5 and Gb ethernet.
You desktop only need the OS drives maybe extras for A/V editing.

Some people have trouble understanding low-cost. There is nothing
inherently bad about low-cost, as long as you know and understand
the limitations.
