I purchased my first RGB Gaming PC, my first Desktop Computer in about 8 years. I picked up the iBuyPower MR9700V2 from Amazon for $629. This is the 4 colored Fan Mirrored front and side panel case, very clean and cool looking. I really liked the case and the price, because I had heard the Ryzen 3 3100 was almost as fast as the higher priced same exact case PC as the Intel Core i7 9700F. Anyway... I got hooked on the look of this RGB PC Case and figured it would do me just fine. This is a Ryzen 3 3100, 8gb DDR4 2666 ram, Radeon RX 570 4gb Video card, 240gb ssd and 1tb hdd with the Asrock A320M/ac mother board and 500w PSU. I built PC's a long time ago, when you could really save money building your own PC, until Dell and HP starting making PC's pretty darn cheap.
Anyway, getting to my advice. I looked at a few video's and with all the wires/cables/fans and such, I did not feel comfortable building my own PC from scratch which is why I purchased what I think is a really cool PC. Could I have saved a lot of money building my own from scratch rather that upgrading a cheap purchase from Amazon. After Upgrades and selling my old CPU and Video Card, the following PC cost me $1141 with Windows 10 Home. I went to custom build PC places like iBuyPower and such, and could not get the same PC setup I have now for less money as well as having all RGB just the way I have it.
I got hooked on all the RGB right away and purchased the 2x8gb Corsair Vengeance DDR4 3200 RGB Memory ($75) to swap out the 1 8gb 2666 that came with the PC. I knew I was going to get another 8gb memory and figured I should get matching faster memory as well as cool RGB. I then was looking around and found the Ryzen 7 3700X with the cool RGB Wraith Prism Cooler fan on sale for $279 at Best Buy and had some rewards bucks to use towards it. So I took out the Ryzen 3 3100 with its current fan and put in the Ryzen 7 with cool RGB Cooler Fan. I then found an MSI GTX 1660 ti with RGB for $259, so I swapped out the Radeon RX 570 for the GTX 1660 ti which is like 52% faster according to the benchmark comparing the two cards.
So.. $629 + $75 + $279 + $259 = $1242 + tax = $1341 - $200 (Sold old CPU and GPU Card)
Total New Computer Cost is $1141
