Computer Parts List

 Case- Thermaltake Core V1 Mini Tower $45-$50, Tons to choose from I like this one a lot.
Motherboard- Gigabyte Ultra Durable GA-H81N w Dac-up USB port- $68-$80
CPU- Intel i7-4790 - $250-$350 Microcenter in store pick up by far the best price
Ram- G Skill Ares series 240 pin DDR3 1600, 8 GB (2x4GB)- $30-$40
Look for low latency cas 9 (faster memory) brand not as important.
PSU- Cosair CX-430M 80 Plus Bronze certified- $45-$55 often with rebate
SSD- Adata USA Premier SP550 120GB 2.5” - $35-$45 (for OS and Music programs)
Brand not as important, pick one with good ratings
WiFi Card- Intel half size wireless mini PCIE card 5100 series thru 7260 series

5100 series is oldest 7000 series newest. I use a 5100 series with good results but it does not have Bluetooth, newer cards have Bluetooth. $9-$30 depending on series
WiFi Antennas- So many options, look for 6Db or higher gain, dual channel (2.4 Ghz & 5 Ghz)
I used these- Super Power Supply® 2 x 6dBi 2.4GHz 5GHz 5.8GHz Dual Band WiFi RP-SMA from amazon $7-$10
USB Header- SIENOC USB 3.0 20 Pin male to USB 2.0 9 Pin Motherboard Female Housing Cable
 From Amazon. $5- so front panel USB will work, they will be USB 2, not usb 3.
Windows 7 Pro- I buy from eBay, make sure it has COA and license key. Once activated you can then upgrade to win 10 pro for free until end of July 2016. $30-$60, pick a reputable supplier, I have bought 3 this year (all different sellers) and all activated just fine.
USB Keyboard- I used ones I had laying around, any windows usb keyboard will work
USB mouse- I used one I had laying around, but any windows mouse will do.
Monitor- I used one I had laying around, motherboard accommodates VGA, DVI or HDMI connections. Pick one you like.

Music storage (tons of options, I chose a external HDD)

I like lacie external HDD's they are rugged and very dependable. There are a lot of good HDD mfg's out there. I use one like this- Lacie Porsche Design P'9233 2 TB. Have used it for over 2 years and zero glitzes, I noted reviews on it are not great so look for excellent review and 2-5TB capacities. Also make sure to have a second drive that is an exact backup of the music drive; you do not want to lose that music!!!! I format my drives in exfat which can be read by both mac's and windows computers, this adds versatility.

You certainly can add an internal HDD to this computer (as opposed to an external one) for music storage something like this:
WD Black 2TB Performance Desktop Hard Disk Drive, highly reviewed on amazon

There are so many options your head will spin; I chose to build a dedicated audio PC with an external HDD and formatted in exfat. Then I can unplug the HDD and burn CD's with my mac to this HDD. It was easy and does exactly what I want.

CD/DVD Burners
The computer case above does not allow an internal DVD burner so you need external one.
Many options pick a USB DVD read/write burner. I use this one: LG Electronics 8X USB 2.0 Slim Portable GP50NB40 it's about $22 on Amazon. Pick a highly reviewed one.

Sources to buy Computer parts
Amazon- carries almost everything, I shop for price but have ordered a lot of computer stuff from there.
New Egg- Great Supplier and carries a lot of stuff, sometimes higher priced, I also have ordered a lot from there.
Microcenter- Excellent store, best CPU prices (by far), but in store only!
Fry's- another great place, I prefer in store to online.

There are a lot of options I only listed a few. Buy from whom you are comfortable with. I like Amazon and New Egg for online and Microcenter (in store for CPU's).

I just built the above computer for myself, and another for a friend. Total cost for just the PC (not the keyboard, mouse or monitor or external HDD) was around $560, this included taxes and shipping
