I built a PC around this time last year and the parts are the following:
8GB Crucial Ballistix Sport Ram
Gigabyte GA-78lmt USB 3 mATX rev 5
MSI GTX 750ti Factory OC TWIN FROZR
Thermaltake Commander MS-l Epic Edition
500w Evga Bronze 80+ PSU
The PC is very basic and probably will get a lot of bash for how underpowered it is but however I think it's pretty ghetto that I scrapped this together for around 400$ (500$ included tax and monitor and stuff) last year (I got the best prices last year, now you can definitely get the same parts for cheaper or better parts for the same price especially since RAM prices have slashed in half. I got the set for around 70$, now you can find it for around 50$.)
The graphics card is pretty garbage, I think they overkilled with the twin frozr cooler on a gtx 750 ti, I mean like who's gonna overclock a low profile card? However aesthetically it looks pretty nice and my build has like a red theme but it looks cheap (being that it is.)
The monitor I use is like barely even like borderline capable for gaming (22" AOC 1080p monitor) it's really small and has only a refresh rate of 60 Hz, it's TN so it's not even IPS.
My peripherals are also extremely cheap with a Thermaltake illuminated membrane keyboard that has macros, it was like 25$ but got it on sale for 10$. (Tt eSports Commander Prime)
And my mouse is a Redragon Centrophorus ~20$
So basically how budget (ghetto) can you get before you start dumpster diving for parts???
