Angels have the Phone Box
Nope, @essenbe, you found an older iteration of what I eventually did. @maranna what will the pc be used for?
Here's an example I just did, without logging in to PCPartsPicker: Intel Core i7-6700, EVGA GeForce GTX 960, Fractal Design Define R4 w/Window (Black Pearl) - System Build - PCPartPicker
Now, it's a mid-tower ATX case, not a full tower; full can be pretty big for some, but the larger case makes it easier to work inside. This case has a window.
The i7 6700 Skylake is the latest Intel chip - might as well be on the bleeding edge!
The ASUS Maximus VIII Hero MB takes 32GB max RAM (4 slots total), but you can start with 16 (2x8) and it would be fine. As mentioned above, you can always add more later.
Now, the MB will have integral NIC for ethernet connection and integral sound connections, so you can hold off on a sound card and NIC card. It also has HDMI and Display Port connections for a monitor. The separate graphics card has 3xDisplay Port, 1xHDMI, 1xDVI-I and supports up to 4 concurrent displays. So, you can hold off on a separate graphics card, unless you're gaming.
The power supply is fully modular, and I think these come with a 10 yr. (5+5) warranty.
Use the SSD for the OS and programs; put your user libraries on the 1TB spinner-makes it super fast!
So, leave out the graphics card for now and you're right around $1000.
Then add in a W10 x64 OS. If you buy a retail version, it is transferable in the future.
Bluetooth: get a USB adapter to plug into the rear.
The CPU cooler will come with a tube of thermal paste. The chip will also come with its own cooler, but you don't want to use that.
Use your old monitor until it dies. Watch slickdeals.net for sales. Go with 23" or 24"! You'll need a DVI to HDMI adapter to use it connected to the MB while you save up for the separate graphics card.
I had a problem with "fax". My older system that I replaced had an internal fax card - I could not put that in the new rig. But most AIO printers have a fax function, and that's what everyone uses now.
I am surprised you have a 64-bit version of Office - are you sure about that? MS don't recommend installing 64-bit Office unless you have a really good reason for it. Please double-check on that.
Once you have your system designed, pick one store you can get everything from, that has a good return policy. @essenbe recommends Amazon. I used a local superstore called Microcenter, only because they are relatively close to me, had comparable prices, and a good return policy. Then make your purchase all at one place. If you have any defective parts, it makes things easier to deal with than parting it out all over the place.
Use PCPartsPicker to select your components. It will only show you compatible parts. The only thing you may need to worry about is the height of the CPU cooler. Just run it by here before you buy.
Hope that helps!
EDIT: Use the DVD Optical Drive from your current system, so you don't need to buy another one.
