Modern Rack Rails in Classic Racks?

Rebuilding here in my converted bedroom office I bought an open 4 post rack off Ebay that lists as 27U but has about 29U of usable space (see link at end of email). The top was meant to be two thick caps tying the two sides together but I'm putting shelf on top for a Compaq TSZ08 reel to reel tape drive. I've found that rack shelves are an expensive thing. My main rack was "only" $200 and most shelves were around $100 each. Then I found this one at Amazon: <https://www.amazon.com/gp/product/B06Y3LZVL8/> for around $45. It's solid and sturdy. The shelf itself is 26" deep and the supports are adjustable for racks of different depths. It's fixed and doesn't slide, however. It may be what you're looking for. I haven't found anything better for less. It's made by the same company that made my rack and now I see I could have gotten it cheaper ($6) from Ebay! Doh! <https://www.ebay.com/itm/Rack-Server-Vented-Shelf-19-Rack-Mount-1U-Adjustable-from-27-31-Shelves/162159828843> If you're also looking for something to use to mount your Proliant (If you don't have the HP rails) then these are good: Full Length adjustable Rack Rails: <https://www.amazon.com/gp/product/B01C4TDF0G> Partial Length adjustable Rack Rails: <https://www.amazon.com/gp/product/B00XXDLHDA> They com in single, two and four packs with slight savings the more you buy. Because of the adjustable nature, they do have some screws which impinge on the roughly 17.5" between the rack rails. I have a few things that fit rather tightly against them but they do flex a bit which allows the item to fit.
