Sub $250USD consolized MVS build [Part one]

I've taken it upon myself to see if it's still possible to put together a low cost consolized Neo Geo MVS. I set an arbitrary price limit of $250 USD (including shipping and tax) and unlimited time.

In addition, I am not factoring in the cost of a 12v power adapter. Not only are the ones you normally get with these systems cheap junk, I have a pile of them sitting around. In addition I am not including the cost of the LIR2032 battery mod, as it's not really needed and again I had the parts.

Last and major caveat, this system will be RGBS only and use DB15 controllers only. So to hook it to a modern TV you'll need a RetroTink, OSSC, GBSC or similar.

Neo Geo MV1C main board (with a copy of Super Sidekicks 2): $116.80 from eBay. Offered 80+shipping which was accepted. I don't really need another copy of Super Sidekicks 2 (turns out I now have three) but as a bundle this was as steal. Took awhile to arrive, but it was a seller I'd worked with before and everything arrived in great shape. This MV1C was missing the plastic shell, but since it's going in a consolized system that didn't matter.

Colsolized kit: $60 + $33.64 for tax and shipping off of Aliexpress. "New Good quality Transparent Acrylic CBOX Shell without motherboard NeoGeo Supergun CMVS Case DIY Kit for CBOX Arcade Game Parts". Sadly no longer available.

UniBIOS preflashed to a SOP chip: $14.03+1.19 tax off of Aliexpress. "Unibios Version 4.0 NeoGeo AES MVS SNK Used In MV1FZ/B/C Arcade Machine Accessories Motherboard Parts". Strictly speaking you don't NEED UniBIOS. But they're cheap.

So, this takes me up to: $225.66 including tax and shipping on all items, which is a solid price point. I'll spend the extra ~$24 on a decent SCART cable.

I have a fair number of projects in the works, and a fair number of work projects. So not 100% sure when I'll be able to do the build. But expect two other parts, part two will be the battery mod and UniBIOS install. Part three will be the final assembly and testing.
