Hefting all of my CDs around when I DJ is a foolish idea. One, a fair number are now irreplaceable. Two, I own over 800 CDs at this point. I think. Last I counted was a few years back, around 750. It's grotesque.

So I got to thinking, "Well, I could simply burn high quality rips to CD and, in a club, where it's all bass anyway, nobody's going to notice." Which would work for most of my stuff, to be honest.

Looking into that avenue, however, I see that I'd pay out my ass along with my best friend's ass to have my CDs converted by somebody else.

"Why, for that price, I could build a machine to do it myself!" I thought. And you know, that's not a bad idea. For about $800, I could simply do it myself.

I'm thinking a dual Athlon 64 box with a pair of slot-loading DVD drives to pull two discs at a time, tray loading DVD burner to sort things out later and for ripping those few mini and oddly shaped discs I have, RAID 1 to secure what work I'm putting into this, and a soundcard to run this vast audio library into my receiver, which may have optical in, I forget.

Thoughts? Suggestions? Input?

don't need that big of a system, one 64 with 4 optical drives.  Nice sound card and a 2 big ass harddrives using built in SATA raid.  One of the opticals can be a dvd burner.

RAID 1 to secure what work I'm putting into this

Just a reminder: RAID is not a backup. RAID is meant for servers that need to be running all the time. They can't afford any downtime if a hard disk fails, so hot-swappable RAID is the solution.

I don't think your MP3 ripping machine needs to be up 24/7. Neither do I think your machine will need the slight performance boost RAID gives you. So skip the RAID and use the money for some high-capacity external hard disks to use for backing up your data.

On the other hand you know more about your needs than I do, so my advice may be entirely inappropriate.

Here's a question: is this machine strictly for ripping and burning, or will you be actually playing music with it?

I like the redundancy of RAID 1 and the idea of portability which a massive external hard drive would grant. I don't need 24/7 performance, but I also don't care to use a few dozen-hundred hours of my life ripping with proper tags to a decent quality to see it all flushed away on a rogue HD failure. I'm being paranoid and looking at worst case scenarios, I know.

Primarily ripping, though, as I said, after that, I'd likely use it for playback and, perhaps at some point, picking up FinalScratch Pro and toying around with that. Nothing video related -- the S-video on my laptop takes care of all of that well enough.

This is pretty cool.  I have a solid state relay board laying around with the relays.  The switching loig seems pretty simple.  But for probably not to much more you could get a cheap little seimens PLC and hook it to a serial port and just write a program that does all the switch logic for you.

No, seriously, I was actually asking, if you're ripping 3 CDs at a time, what's the minimal processor/RAM you'd want?

Also, for the HDs, I'm thinking something more along the lines of 10K RPMs to handle all of the file creation occuring at once. Anyone find fault with such logic? P.S. Excepting the insanity of pricing on 10K SATA drives. Holy mother of Hell.

A 10K RPM SATA drive is sweet; I use one. Apparently it now comes in bigger sizes than the 37 and 74 GB varieties WD had when I bought mine. Cuts seek times in half, and if you're loading up the hard drive with lots of files really fast you'll get the biggest speed benefit from one of those.

You can probably get by with an AMD64 3200+ for the CPU and save some money. The price increase in upgrading to the 3600+ isn't worth it in most cases, and you're likely going to be limited by other factors than your CPU.

Finding the right motherboard is going to be a bitch. You'll probably even want to look for onboard video to save money, unless you have a spare graphics card sitting around.

If ripping speed is your top priority you also may want to look into PC3500 or PC4000 RAM. I know, it's typically bought by hardcore gamers, but the speed increase is pretty nice. Then again, I know fuckall about MP3 ripping and it may not be all that memory intensive.

Well, I think I'm crossing into bold, new territory here, unless somebody else on this board has endeavored to rip 800+ CDs, three at a time.

This may be a fine motherboard, the Asus I've and used before having never let me down, featuring the SATA RAID, on-board audio, and some manner of instant music.

So, $150 for a 64 3200,
$90 for a lesser board, $150 for a pair of HDs, around the 160 gig mark, $100 for a gig of RAM, $50 for a pair of these slot-loading CD drives for the primary ripping (unless somebody can find something better, slot-loading to save me the hassle of trays), and another $75 or so for case and dual layer burner.

And yes, I've a shitty video card I can pull out of my old Athlon 700. It's old and shitty, but displays video. Oooh, though... do I want to get a small LCD I could hang near the box? Nothing big; if I could find a 10" or 15" widescreen cheaply, I'd probably do well enough.

So, further opinions on bits and specs? Because this is something I seriously need to do, if only to catalogue all of the shit I have strewn about.

I just put together a quiet audio box with an Athlon Mobile XP.   Bought most of the parts from  Newegg.com and it seems to be working pretty well.  Building computers is fun.  Anyway, you're going to want good ventilation in the case.  Having all those drives going will create some heat.  It looks like those CD drives are SCSI.  Unless you're planning on buying a SCSI controller card they won't work.  Pioneer made some slot loading DVD drives.  You may want to look for them.  I think you're going to have plenty of power to do what you need.      Just make sure to test the memory you buy with http://www.memtest.org/">Memtest.  Unstable memory is no fun.  

When I rip my CDs I use http://www.exactaudiocopy.org/">EAC to rip to http://flac.sourceforge.net/">FLAC.  EAC does really nice error correction and can smooth out skippy discs.  FLAC is lossless so it's a bit perfect copy of the CD tracks.  They take up a lot of space (300-400 meg an album) but you can always reencode to a smaller format for portability.  I just like the fact that if I lose a CD I can burn an exact copy of it.

I'll vouch for ASUS as well on the mobo and that one in particular looks good. CPU sounds right too. To be honest I'm not all that familiar with AMD so I could be wrong.

But you're going to spend $180 on a single 10k RPM hard drive, and that's only 74GB. If a RAID setup is optional you could use the fast HD as a primary and just stick  a bigger, slower IDE drive in the box and back it all up in one long, hideous transfer (I'm thinking, set it before you go to bed). So you'd have backup but still operate from a speedy drive, and swap files as necessary. Frankly, 74GB of music should be more than enough but then again I may not have a full grasp of the scope of your music collection.

Cannibalizing an old video card will save you a bundle though. As for a small LCD monitor you'd have to look into a specialty LCD sort of thing to get something small enough to be really portable. Samsung has a number of higher-end monitors which fold up nice and small, though. Bit on the pricey side I'd imagine, though a quick perusal of Newegg doesn't turn up any.

I'm noodling on some disk space calculations.

1000 CD's, 650MB per CD = 650 GB (pessimistic)

320kbps MP3's (high) = .23 of CD filesize, or 150GB
192kbps MP3 = 91GB

So.. you'll need some pretty serious hard disk space.  but I don't predict hard drive space as a serious bottleneck.  i'm guessing the bottleneck will be vying between CPU or CD drive speed.

I think software is going the be the most important thing.  you're going to want a setup that can rip CD's as fast as you throw them in the drive, with not other interaction.  Not only that, but you're going to want something that can populate the MP3 file ID's with reasonable info and store all these MP3's in some sensible organization.  That will be the hard part.

I've considered ripping direct disc images, but not wanting to shell out for a terabyte of harddrive, I've had to sadly dismiss the concept, unless somebody has an inside track on massive amounts of storage to be had at a good price.

Old though it may be, CDex is what I've used for years. Good configuration and handles copy protection like nobody's business.

Toward the actual construction, though, we can discuss best formatting (mp3, mp4, ogg, something else).

While you're ripping all the CDs, open the case and point a box fan at it. When you're done with all 800, take the extra CD drives out of the computer--you don't need them anymore. I don't think you need to worry about overheating.
