Not sure where to start?

How old is your son? A younger man would probably appreciate some colorful lighting. The two most popular cases here are the Lumos and the Lynx. The Lynx comes with lighting included and is still less expensive than the Lumos, which requires pricy fans to illuminate to it's best effect. They are both good, sturdy cases.

So here's a sample of each. You have room in your budget not to skimp anywhere, so I have selected 10 core processors as the 2 extra cores may benefit the dual headset image. The GPU is extremely powerful newest generation from Nvidia. It is probably some overkill now, but it will not falter if you upgrade the headset to an extreme resolution in the future.

Lynx build, $2697:   Config ID 3453133


Lumos build, $2992:   Config ID 3453126

To view these in the configurator (where you can make changes), select the "Load Config" option at the upper right of the main page and copy an paste JUST the number in the window.

You can see the difference between the two cases as to price and need to add the colorful fans to the Lumos because, aside from that, the two builds are pretty identical. The prices above reflect the current discounts which are not yet taken in the Configurator.

I highly recommend the storage as suggested. The Samsung 970 PRO NVMe SSDs have a proven track record and are the very best choice for your primary operating drive. They are 5 times faster than the regular SSDs. (Called SATA.) The 1 TB 860 EVO SATA SSDs will allow plenty of room for a games library without breaking the budget. Frankly, the larger SSDs are too pricy here, and storage can be added very easily whenever needed later.

If there was anything else these builds MIGHT benefit from, it would be another 16 GB of RAM if you want to pay. It's not needed for now, and not for the immediate future, but it's reasonably priced.

Hope it helps, and feel free to ask questions!

Pleasure.
