Well I'd say that for a budget of $1000 you could easily build a PC that exceeds your requirements. The problem is that if they're making you go through a company to replace it the price will be inflated by their build price. I would suggest the following, most of which was already suggested below. My rig excluding my extra monitor and extravagant keyboard/mouse setup ran me about $1400 give or take, but I went for high brand parts such as MSI for a lot of my pieces. Since your brother builds computers I'm sure he'll tell you the same thing, but I can't emphasize enough that going cheap is more often detrimental than forking out the extra couple hundred for quality parts.

Processor: Intel i5 - They already have out i7s which is what my computer is running, so if you can spring for that great get one, but an i5 will do you just fine, the i3s are a bit weak imo so they'll have a tougher time when looking at newer games that you may or may not be interested in. AMD does just fine, I've always had Intel for mine so I see no point in changing, but from what I understand intel will serve you better when it comes to multi-tasking, which I do chronically.

Graphics Card: Since I currently have a gtx 970 in my computer, it runs great, I highly recommend the GTX series, for the specific number you'll want to be looking at 670s and higher, they've been a dream for me and the supporting programs that come along for monitoring new drivers and such help you stay vigilant with updating your drivers. I have an MSI card as I'm a pretty big fan of the company and have had very good luck with their parts. So I heartily recommend looking into them as a possibility.

Motherboard: As long as you stick to a main brand motherboard you're fine. It was already said below, and I can't echo it enough, DON'T BUY GIGABYTE. My friend went through 3 motherboards just trying to put his computer together, they literally came dead on arrival with bent, broken, and missing pins. The third board he bought was from another company. Mine, with my loyalty to the company is an MSI board, so again I recommend them. Brand loyalty FTW.

RAM: I have 16GB (8x2) it's beyond what I'll likely need for most things unless I intend to stream heavily. 8gb will be plenty, but again if you can spring for the extra, you might as well. I use G.Skill for mine, they're cheap, solid, and unless you skimp on a power unit you won't have issues.

Power Supply: Similarly to what was said below, make sure to use a branded PSU the cheap asian imports don't work right, won't give you the power it actually states, and WILL ruin your computer

My computer runs League at around 240FPS, dipping down to 190FPS during a 5v5 teamfight when everyone is blowing all their skills, my settings are all maxed with shadows turned off (hard counter for Zed, haha). If your parts cost ~$1000, expect your end price to be around $1200-$1400 the markup for them building it it's pretty substantial depending on the company, but you'll at least have their guarantee that it'll work for however long.
