Yup, you don't have to do OEM. I have the Cooler Classics aftermarket part at half the cost; it works well enough, so unless you're a purist with disposable income, you can make it work using other means. I'm also convinced that you can use other parallel flows with some custom fittings to make it work. It seems possible, though beyond my expertise. I, however, have decided that my rig gets OEM-only parts because I'm trying to get it to a near-restored state, so this makes sense, though there is some risk.
OK, so Binmahmoodstores:
1. They're in Yemen, you have to accept the risk that your money may be lost. Not legal advice, but it seems these purchases will not paint a target on your backs in terms of buying from a country that's considered an enemy state. At least based on my quick research.
2. The ordering process is either through Instagram or WhatsApp, with no website.
3. They're responsive. They asked for my info, printed it all, and then took a picture of the item with that info, so it shows they're at least willing to go that far.

4. Total cost $790, go on eBay, someone is selling a POS that's half bent for $800.
5. Again, there is a risk of never seeing your item if it gets damaged, lost, or money walks, tho the last one seems kinda not likely on the count of their reputation through spoken words.
6. I've seen posts here of others buying from them, and the mechanic shop I worked with also endorsed them, good enough for me to proceed.
7. Shipping: Yemen, Sana'a to Oman, Salalah by land, it takes 6 days. When the shipment arrives in Oman, Salalah, it is shipped via DHL, and we need another 6 days for it to be in your hands.
8. Only forms of payment: Western Union or MoneyGram, again, because of the Geopolitical scene.
I've wired the money, once they collect, they'll ship, and I may or may not post an update in a week or two, Inshallah.
