Need Advice for Virtual Instrument PC

I am thinking about building a rack mount PC for playing virtual instruments (VSTs) in a live setting and I'm looking for advice.
It needs to run Cubase 5 64 bit and be able to play back large sample libraries such as Hollywood Strings from East West or Morphestra from Sample Logic.
I have no plans to overclock at all.

It would be based around the ProFire2626 firewire audio interface from M-Audio.

Also, It needs to be portable AND protected. This 4U Studio Flyer case from SKB should do the trick.

The ProFire2626 will take up 1U in the case and that will leave me room for either of the following cases.

iStarUSA D-213-MATX Black Metal/ Aluminum 2U Rackmount microATX Server Chassis 1 External 5.25" Drive Bays

iStarUSA D-313-MATX-M1-Blue Metal/ Aluminum 3U Rackmount Compact Server Case

It would be nice to be able to get away with the D-213 since it is only 2U high but I'm not sure how tight the fit
is going to be on everything.I'm not sure which way to go here. Will these cases run cool enough?

I'm planning on using an Intel Core i7-930 with the stock cooler on a MSI X58M Micro ATX Motherboard
with 12 GB of G.SKILL Ripjaws Series RAM

For hard drives, I picked out an Intel X25-M 160 GB for the OS drive (located in the 5.25 drive bay)
and 2 HITACHI Deskstar HD32000 2 TB drives for sample storage (located inside the drive cages.)

The video card doesn't have to be great so this low profile HIS H545H512 Radeon HD 5450 should work.

It needs a DVD drive for software installations and an extra network card for slaving it to other machines.

SAMSUNG USB 2.0 Slim External DVD Writer Model SE-S084C
Intel PWLA8391GTL 10/ 100/ 1000Mbps PCI PRO/1000 GT Low Profile Desktop Adapter

It doesn't need to be quiet but it shouldn't sound like a jet taking off either so I'll
replace the stock fans.

SilenX IXP-54-14B 80mm Blue LED Case Fan

The power supply is the part that I'm most unsure about. This Antec looked like it had enough power and the fan location would be exposed
instead of being covered by the case. I wish it was modular, though.

  1. ^ Did you check out the i7 860 ?? IMO that would be a better choice...
    Reasons -
    1. 95W TDP compared to 130W of the i7 9xx so less heat and less power consumption...
    2. As you wont overclock, the i7 860 will run faster in Turbo than the i7 930...

    And as for the case, if space is not a constraint, stick with 4U rather than 2U...
    And check out this case...
    ARK 4U-500-CA Black 4U Rackmount Case 3 External 5.25" Drive Bays
  2. I see what you mean about the i7 860. The ARK 4U-500-CA case is cool but it won't fit into the 4U Studio Flyer case I was thinking about since the depth is over 15". Thanks for your input. It gave me some other options to research.
