Am I being greedy, or does this sound reasonable?

About a month ago I decided I was gonna build a gaming pc. I was just gonna save up my money. My brother said that if im feeling impatient then he would pay for it now, and I could pay him back. So I picked all the parts I wanted, and it came out to around 1600. Then he changed his mind, and I was just gonna save up again, but its going to take months. The thing is my grandparents left us around 90k each. My brother and I put together our money and bought a mobile home in 2017. I moved out and sold my brother my half, so he owes me about 50k. I put my trust fund in my savings a while ago, so I have full access to it. It's only about 23k, but I was thinking of taking out 1600 for the pc, and then buying the parts and eventually paying it back. Like 20-30 a month. I was gonna tell my brother this, because he knows what parts I want to buy, and he was gonna help my put it together? I don't want him to think I'm greedy. Am I being greedy? Should I just do it the hard way, and save up?
