Well, Starting this month, I will draw about $50 from my bank to paypal for saving for each month. I might should get raise this month. If I do, I might will raise to 75-100 depends on how much I collect. I want to save for 6 months at least. I want to look up early so I can get ready to buy and get it done. If I buy cheap and powerful PC then I might save some left and add more later for new upgrade or whatever.
Ok, it took year for me to save up for PC/Mac, including built on my own.
First, you need look for good case with enough room to upgrade, the cheaper cases on newegg are easy to broken and worst case, you cannot return if you break it, even virtually, it isn't your fault because it isn't durable.
For example -
Newegg.com - COOLER MASTER HAF 922 RC-922M-KKN3-GP Black Steel + Plastic and Mesh Bezel ATX Mid Tower Computer Case with USB 3.0 and Black Interior
That's good case.
Other one isn't good -
Newegg.com - COOLER MASTER Elite 311 RC-311B-SWN1 Silver Steel / Plastic ATX Mid Tower Computer Case
It will break so easy if you do something is wrong and you could get cut like I did last year.
The case that I bought last year is excellent.
Newegg.com - COOLER MASTER Storm Sniper SGC-6000-KXN1-GP Black Steel, ABS Plastic, Mesh bezel ATX Mid Tower Computer Case

It is important to read some reviews that considered as critical, contain both of pros and cons.
That all you need to list.
1) CPU
2) Motherboard
3) Case
4) RAM
5) HDD/SSD
6) Video card
7) PSU (Power Supply Unit)
8) Monitor
9) Optical Drive (You may not need if you know how to install Windows from USB and download all games digitally)
10) CPU Fan (The stock fan maybe ok but recommended to get better CPU fan for max cooling performance)
11) Network card (The network built in some motherboards are okay but some of them are bad so you need dedicated network card)
12) Thermal paste (Most CPU already have thermal paste as prepackaged but I prefer to apply thermal paste for better cooling performance)
First time to build the PC can be frustrated and you will be successful if you follow instruction manual to build the PC or ask your friend for help.
