DAW all-in-one box vs. PC - from MY perspective.
I've worked for years as a computer tech and network LAN/WAN tech, and I have a few of my own. But now I want to make music, not troubleshoot a computer system for music. You have a lot of choices and a lot of decisions when it comes to using a computer system for your recording. Mac may be better, I don't know, I only know PC and for everything I've ever used a PC for, I'm glad it wasn't music.
Your choices are so many, and so many things can go wrong, that I just decided to go with a system that already had those things worked out for me. It's basically been designed/engineered from the ground up to do the one task that I want it to do.
I don't want to have to design and assemble a computer system on my own to do that. If there is a problem, like a tiny glitch or latency, where would you start to troubleshoot. The hard drive? the hard drive's speed, buffer, the defragmentation of the hard drive, ever look at a newly installed operating system on a hard drive with a defrag program? It's fragmented from the installation, also, the system swap file may also be fragmented, and can you control it and put it up front on the drive where it would be most efficient? Not that I know of, but oh, I'm sure you can find that info burried in some user group somewhere on the internet and they may even have some shareware that can do that job. Go search, not me, I'm already recording out of the box.
Sound cards, there are many, but before that step, how much ram do you need? what processor do you need? can you skimp on any of these things? I have no idea, but I'm sure you can ask some questions and find out that MAYBE you can use and AMD chip that's cheaper than an Intel chip, like the P4 and get away with saving $100, but then, why skimp on the money and hardware? this is your music we're talking about, so go for the biggest, most expensive hardware you can afford.
Software. There must be at least 10 choices here from shareware/freeware to $1000+ programs that will have you using your mouse to move faders, or get a box that usb/firewire will transfer your control surface data to the PC, at what rate? usb 2.0 or firewire? I don't know, but I'm sure there are plenty of people who will give you their advice on which one, so you can decide, oh yea, don't forget that you will always have the option of upgrading parts of your system if you need more power, or if it has a problem.
what could freeze your system and have you reboot and loose you data? (music) Well, let's see, memory corruption, applets misbehaving, oh yea, you wanna use this PC for something other than your music? Like word processing, or internet access, so you need a fire wall or at least anti-virus software, and maybe you need to disable all the software while your music software is running so you don't have any chance of one of those programs messing it up, email?
Do you already know how to assemble a system? What version of what motherboard are you going to choose? how many pci slots? how much ram on the video card? will your monitor be picked up thru your electric guitar pickups? so get a flat screen for 2x the price, how big?
This is only a few considerations, good luck, but remember there's plenty of help onthe internet if you need it....
or spend 800 to $1000 and have a box that is a computer, bTW, but has been designed and engineered from the ground up and tested to work out of the box. Can you do what you can do with plug-ins and software and pro tools or nuendo or cubase or cakewalk? no. But do you want to?
These are only my own thoughts about if I wanted to go the PC way or the all-in-one box way. I got my box, put it on a table, hooked up a mic and recorded all in 2 hours from leaving the house to coming back and working.
Of course if you want to learn pro tools, that's a different story. Do you want to learn about software and computers? do you want to be an engineer? or do you want to record, over dub, mix, burn a cd and go to a real studio when you want better quality and a producer?
I'm not really saying that any one way is better than the other and loads of people want to f around with PC's but I don't, didn't, would rather never have to again....
