Pretty straight forward really. I wanted a mobile computer for LAN gaming sessions with friends and family, and I wanted it for cheap. Luckily I had a lot of spare components lying around from older builds, allowing me to keep the budget ultra low. $182 to be exact. Already had a 256 GB SSD, 500 GB 5200rpm HDD, 750W PSU, GTX 980, and 16 GB of DDR4 3200 RAM. Grabbed a Thermaltake Core V1 ITX case for $50 and got $20 back in the rebate offer, making it cost $30. Yesterday, I went out and grabbed an i3- 6100 processor and an ASrock H-1110M ITX/ac motherboard, when bought in a combo takes off $30, also adding $5 off in a promo code, making their combined total $152 after tax. That was all the buying I needed to do, 3 parts for $182. Threw it all together last night, and with minimal issues now have it up and running. Can play every game absolutely fine, and unless I try to play a newer Total War game on ultra settings, i don't foresee running into any problems anytime soon... And if that problem were to arise I can throw in an i5-6600k I have when i decide to upgrade my main system. No big deal, given how low the cost of this build was. Temps idle in the high 30's low 40' but not much can be expected from stock cooling in an mITX chassis. Its a complete hodge podge of components, new and old, overpowered and under powered, when compared to each other, but it does what I need it to do and was a minimal cost to me.
The price breakdown of this build in the parts list is not what I actually paid, will try to update that when I have time to scour through old boxes.
BEWARE: To fit an MSI GTX 980 into the Core V1 You will have to cut a slight piece of the chassis framing on the V1 in order to plug in the first 4 pin power connector...
