if it helps heres the RAM. Its a different brand from the original one that was the T-Force Vulcanz stick

If you did want a laptop I would totally snag this or this. Both have enough hardware to play current AAA titles and will last for a few years for sure

If you do want to part out a PC to build Amazon might not be the most cost effective so check a bunch of different sites to make sure before pulling the trigger (including microcenter if there's one near you). Here's a decent start list though:

CPU: AMD Ryzen 5 3600 $199.99

GPU: Zotac RTX 2070 $556.43

Mobo: Gigabyte x470 Aorus Ultra Gaming $124.90

RAM: 16GB Corsair Vengeance 3000mhz $69.99

Storage: Samsung 970 Evo m.2 nvme 500GB for OS/select programs $89.99

2TB Seagate Firecuda SSHDD for library storage, if necessary $59.99

PSU: EVGA 650W, 80 plus gold rated fully modular PSU $97.06

OS: [OEM Win10](https://www.amazon.com/Windows-Home-English-Language-Product/dp/B07TW6G6JP/ref=sr_1_7?keywords=windows+10&qid=1563210474&s=gateway&sr=8-7]. $72.00 Not need if you already have. Pretty sure you can get even cheaper OEM copies out there. Or y'know, other means. Or Linux, etc

Total: $1270.35 including the OEM Win10 which you may or may not need

Missing items: monitor, mouse, keyboard, case. Compared to the prebuilt at $1499.99 that leaves you $229.64 to get a case & any necessary peripherals, upgrade any items on the list, or just pocket the 'savings'

The ibuypower one linked doesn't appear to be that bad. But when reading the comments there are people who got the 8700k version for $1350 (currently $1433, one you linked "on sale" for 1499.99)...so pricing might be misleading. Also keep in mind SI's need to make a profit and usually skimp when it comes to things like cooling, storage and motherboards. I can't tell what mobo that has, but it shouldn't be much of an issue unless you want to overclock, probably not as good components and features as what I listed though. The cooling is actually pretty nice with the cpu watercooling at that price. But not sure on how it is for the other components (ie system case fans). The storage is a bit shit, with a smaller sata ssd and a smaller much slower mechanical hdd. The RAM isn't much better, going off amazon reviews it's basically no name ram at 2666mhz. Also they use a generic 600W psu and apparently the included mouse and keyboard stink. So gotta take the good with the bad but the one I price out looks like a much better option across the board and leaves you room to pick and choose certain upgrades n such

bestbuy wants $90 for 8GB of 2400hz ddr4 ram, they want $200 for 16GB of ram vs amazon's half of that. the only people who should be going to best buy for computers are folks who think this is a good buy

Also speaking of rams, check the discount on these babes https://www.amazon.com/Corsair-Vengeance-3000MHz-Desktop-Memory/dp/B0134EW7G8/ref=mp_s_a_1_3?crid=19TE3O1IPRRG9&keywords=ddr4+ram&qid=1554458409&s=gateway&sprefix=Ddr4&sr=8-3

These were the items i was looking at:

https://www.amazon.com/AMD-Processor-Wraith-Cooler-YD1600BBAEBOX/dp/B06XNRQHG4/ref=sr_1_1_sspa?s=electronics&ie=UTF8&qid=1506156352&sr=1-1-spons&keywords=ryzen+1600&psc=1

and

and

GPU and CPU you can buy on amazon that’s pretty basic. I’d get some really good high speed ram because ryzen loves to use that high speed ram for some reason, it runs really well on 3200+ ram.

Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3000MHz C15 Desktop Memory Kit - Black (CMK16GX4M2B3000C15) https://www.amazon.com/dp/B0134EW7G8/ref=cm_sw_r_cp_api_i_AdsIDbVDBCJFY

Edit: 3000mhz will probably suffice.
