Let's see if we can't get you a
little bit closer to answering your question than Mr. Philosophical.
There are serious constraints with laptops. The processors are slower, less memory, smaller hard drives, and the expansion options are non-existant. Plus, they are very fragile. And for all of this you pay a premium. Only buy if (a) you absolutely need one to make money or, (b) you don't give a damn about throwing money around. Purchase only from stable companies with no-fault extended warranty repair.
Broadly speaking, a desktop is a desktop is a desktop. It doesn't matter if HP, Dell, IBM, or your local Mom & Pop sell it to you, though I would stay away from Sweetwater or other vendors who market a "audio tuned computer!", you're paying for marketing bullshit. You can also, with
relative ease roll your own. You will find a lot of people who will say, "Well, I made one, anyone can do it.". You, however, just may lack the comfort level or the dexterity and paitence to throw one together.
Kind of a neat middle-of-the-road option is to go with a vendor that will let you pick the parts you want and then throw it together for you. For example, MultiWave (
www.mwave.com) sells to system integrators but will also build your's for you for, last I checked, about $75. You pick out the zoomy case, etc., and sit back for it to show up. They also have a good RMA policy.
The components that you will need if you roll your own or have it custom assembled (by whoever) is to have a handle on just what pieces go into making a PC. So, for those who care, here you go...
- First, choose your budget. If you can't spend $1K, I highly recommend stopping here and checking out Dell.
- Second, choose your processor. You need to do some research here, and I don't mean asking your friends. Does your audio software like AMD? Do you have a hard-on for Intel? Check out www.anandtech.com and www.tomshardware.com for invective and opinion.
- Now, find a motherboard that supports your processor and has the features that you want. Now is the time to make sure you are going to be able to support those snazzy hard drives, multiple video cards, and latest and greatest Firewire or USB devices. You DO NOT want to have to stick an expansion card in because you forgot to get a board that supports Firewire, or decide that you need 4GB of RAM and find that your board only allows you 1GB. This is also an area where you do not want to get cheap. Stick with top brand motherboards and stay far far away from the crap ones. Note that this does NOT mean that inexpensive motherboards are bad. A MSI motherboard is a top brand, regardless of whether it costs $75 or $200... and the $75 motherboard may do exactly what you want.
- Throw on the memory you want. Lots of people get religious with memory, say, for example, that only Kingston or some other brand will do. Horseshit. I have always gone with generic and never been sorry. Still, it's your money.
- Your motherboard will support a certain type of video card (it may even have built in video, which is kind of nice). Do NOT buy the latest and greatest. You pay blood through the nose. Do some research, and buy one or two levels below the cutting edge. There are two families... nVidia and ATI.... six of one, half a dozen of the other.
- Get your hard drives. I favor Maxtor, but only because I am familiar with their utilities. Hard drive controllers are always integrated in the motherboard. There is a market for expansion HDD controllers, but you most likely will never need one... cheaper to replace the mobo.
- Pop in a couple of DVD-RWs or DVD/CD-RWs. I recommend you stick with good brands here as these tend to be high failure rate items. I've replaced optical drives more than any other component (other than keyboards and mice).
- Now, hopefully, you will have an idea of how big and how quiet a power supply you are going to need. Do not skimp! Start at 450 watt and seriously consider going up.
- You are now ready to choose your case. Your mobo will have a certain form factor (AT, ATX, BTX, Mini ATX, etc.). Choose a case that will accept your form factor. Many cases accept multiple form factors.
- I recommend that you throw in a floppy disc drive. Cheap and often useful. Occassionaly essential.
- Get a keyboard, get a mouse.
And have fun! Lord, I sure love this shit.
P.S., Stay away from BTX... too new.
Luck.
