Or, Putt, you can build your own. These are all available, and sourced, from Newegg Canada.
Star with a Case. Lian-Li is one of the best case manufacturers out there, and this is lower priced for their line of gear.

Next, you need a power supply. I recommend Seasonic. I've have very good results from their power supplies.

Next, you'll need a motherboard and CPU. I am going to recommend AMD CPUs for you, since pricing is usually better.
Personally, I like Asus for my motherboards, they are usually reliable and I don't have any problems with them. This one has built in graphics and 3 PCI slots, allowing you to use your 2496 card.

For the CPU, I'm spec'ing the AMD Phenom II Black Edition Quad Core processor running at 3.2GHz, which will provide for everything that you would want to do.

For RAM, I like several, Corsair, Patriot, and currently I'm using OCZ in my primary computer. This is a 4GB kit, but you can buy two of them and get 8GB, which will suit everything you do. I do like 8GB of RAM in my computer.

You'll need Hard Drives to store everything on. I prefer Western Digital right now, although Seagate is also very good. I have both in my computer. Of the Western Digital, for my server, I use the Western Digital Greens, but for my main computer, I use, and recommend the Caviar Black series. Two 750 GB hard drives will do the trick for you, one for the system drive, one to store audio on.

You'll need a CD/DVD burner. LiteOn or Samsung are usually the least expensive, and both work just fine. Here's a nice OEM Samsung.

The motherboard has built in video, so you will not need to use a separate video card. However, you can buy one if you wish. I will not make a recommendation for one, however.
You will need an Operating System. I recommend Windows 7 64 bit. Microsoft offers the OEM for System Builders which is just fine for you. The only caveat of this is that there is no Microsoft support included in this product, but then again, I've never needed any, so it's not a big issue.

You could also buy a Combo deal, which gives you the motherboard, CPU, hard drive, RAM, case and power supply all in one, which is a pretty good deal. You will still need to buy the O.S., however. You will also need to add a CD/DVD burner, same as recommended above. I would recommend adding a second hard drive, as shown above.

Pricing on the left is $Can for the cost, and pricing on the right is shipping costs.
